The mystery wasn't solved yet, but the students decided to leave school at once when Sohye started crying. I.M scolded them for terrorizing her. They didn't want to be a bully like her, so they stopped when they thought it's going too far.

"By the way hyung, we need to buy supplies for our wine making tomorrow." Baejin asked permission because Seongwoo would never trust Samuel or Hyeop on whatever it is that they say. Baejin's an honest guy, a good one too. They said yes right away.

Besides, Seongwoo needed to visit Donghan anyway.

Both Donghan and Seongwoo's cards are cut off by now, Seongwoo's job at Hotline Bling is the only thing that's keeping him alive. He doesn't reply to his mother anymore, and don't meet up with her. He wants to be alone right now to think.

"Tell him 'hi'." Daniel said.

"Tell him I said 'hello' too." Youngmin followed.

"Hi to who?" Seongwoo asked.

"To your evil brother of course." Youngmin muttered.

"But how did you know?" he asked because he didn't tell anybody about the fight, though Baejin did told them about the agents following Seongwoo and Chungha.

"Daehwi said he's been drinking again. We just thought you're taking care of him." Daniel informed. Didn't Seongwoo know?

On second thought, 'why would Donghan tell him?'

Donghan's been cleaning Club Hollywood to get money for food. He's still angry with himself for telling his father about Seongwoo and Chungha. What's bothering him most was, Seongwoo's still nice to him.

"I'll tell him you said 'hi'." Seongwoo muttered before rushing to the abandoned hospital. It was too early to be there of course.

Jaehwan and Sewon are already playing the guitar on the entrance. "Dude!" they waved at him.

Seongwoo greeted. He entered the club knowing that Donghan's already at it with moping the floor before people actually come to party.

He was right, Donghan's already sweaty, doing half of the dance floor. Seongwoo took off his uniform, changing to normal shirt and jeans to lift the chairs and mop them. They always do it at this format.

The bartender was also wiping the shot glasses early.

"If you kids are thirsty, just don't be shy to come to me. All in the house for two handsome young men." he said making the two smile.

They don't look alike for brothers but they're both handsome for sure.

Next one to come inside was Kim Yongguk who brought his cats to play at the wide place. He's only here to study for a while because Sanggyun's allergies with furr was arising again. It's hard to keep cats on a place where someone's allergic to them.

"Sanggyun?" Donghan asked making Yongguk nod before looking back at his assignment.

"Wow! Cats are allowed here?" this handsome guy asked, appearing on the bar, holding the same blue drink that Minhyuk always serve.

"Yep." Yongguk replied.

Seongwoo stared at him trying to recognize him. It's like he's seen this guy before.

"Cats are allowed here before the fun starts, not during. Because they might get lost and it's hard to look for cats in the dark when they're black." Minhyuk told him.

"You have cats, Wonho hyung?" Yongguk asked. Wonho, to Seongwoo it sounds familiar.

"One, her name is Scarlett." he bragged.

Minhyuk rolled his eyes as soon they started talking about cats. Wonho goes overboard with this topic.

A group of guys entered the club while making laughing sounds. They all look scary, then Seongwoo recognized I.M, he's one of them.

His teacher can be seen underground. How can they make it to graduation, if all the teachers who are willing to apply on Seoul High are these rebels.

I.M met his eyes and recognized him right away. "Ong Seongwoo! My responsible student. My lost son." he gave Seongwoo a man hug as a greeting. Donghan at the back was now trying to figure out how his perfect brother who couldn't do anything wrong is now I.M's lost son.

Of course Donghan knew these people. He see them often, at night when all good kids are already at home studying or sleeping.

"How is that you're lost son? He's so handsome." this tall skinny guy questioned jokingly. Nobody can deny that his proportions are for modeling. But he can't be a model, because he's right here with these guys.

"What? It's identical." I.M insisted, pulling Seongwoo's small head to his side by side, to see the resemblance. There isn't, I.M was aware but he likes Seongwoo.

He's a good kid. He made I.M's first day smooth with Daniel ruining everything he can grab.

Also this one familiar new teacher came in holding a box of pizza went to Yongguk's table, before taking all slices of pizza, layering them like a cake before he took a bite.

No one can really tell if he's staring at Yongguk because his eyes are so small that they look like slits.

After he swallowed, he pointed at his expensive looking wrist watch. "It's 8PM. Class hours are long over." he told him.

Yongguk shook his head at his advise.

"Jooheon, just leave the kid alone. You don't get to tell him how he should manage his time." Wonho told his friend.

"This is why we always get hurt. We make time, we give all the effort even when we know that they won't do the same for us." Jooheon responded making his friends roll their eyes.

"Good kid. Just study and ignore him." Wonho told Yongguk.

"What is he even talking about?" Yongguk muttered while shaking his head.

"Trust me, life would be more peaceful if you don't know." Minhyuk told him.

...

Samuel and his cousins were looking for the materials they were supposed to buy. He saw apples. He searched the internet if he can use apples to make wine, and it is possible. Better be different because his cousins are now buying grapes because that's what usually wines are made out of.

"After this let's go to the takoyaki restaurant." Hyeop told his cousins. He wanted to see Mark Lee so badly. He wanted to show him his score on this morning's quiz.

Even now that he's no longer his teacher, he still wanted to impress him.

"You think Who has money for takoyaki?" Baejin asked as soon as they approached the counter. They're about to pay for the materials they're going to use for tomorrow.

Since Seongwoo's card was cut out of service, they can't free load any longer.

"Yuta will treat us takoyaki." Hyeop said it as if he was sure, but why? He might be close to Mark lee, but he's not close to Yuta.

"And if he's not going to treat us?" Samuel asked. He wanted a sure ball, not a wishful thinking. But when it comes to Kwon Hyeop, he wouldn't something he's not sure of.

They all paid for the materials and followed Kwon Hyeops's lead. They stood at the bus stop to make a phone call. Hyeop dialed a number but they didn't who he's calling.

"Noona, sorry for calling, but are you free tonight?" he asked.

Jihoon glanced at Samuel, making shocked expression. "Is he cheating on Doyeon?" he whispered both at Samuel and Baejin. They didn't believe it. This guy can never cheat on Doyeon, but who is he calling?

"We're ready to go." Hyeop told them, just in time for the bus to arrive.

As soon as they got in front of Yuta's restaurant, this older girl was already waiting for them. She was smiling at Kwon Hyeop.

"Sana noona." Hyeop waved his hand.

"I'm pretty sure he doesn't have a sister." Jihoon told the others.

"It's a Japanese restaurant. A takoyaki restaurant. Do you know that the takoyaki capital in Japan is Osaka? My hometown. Just the smell makes me feel at home." she said excitedly.

"Feel at home, because you're going to marry him soon." Hyeop muttered.

"What?" Sana asked.

"I said, what are we waiting for?" he lied barging inside the restaurant.

They were surprised when almost all the student body were there eating takoyaki, and chatting with their former teachers.

There are no vacant seats available, even Sana wanted to just go home and rest. Staying would be nonsense because it seems like nobody wants to give seats even if they already finished eating.

Why? Is there a fast wifi connection here?

"Heeey!" Mark Lee greeted them. "It's pretty crowded right now, but since Hyeop is here, you can use our personal kitchen." he showed them the way inside this smaller dining table.

"Instead of making your own takoyaki, we'll just cook it for you and serve them when they're done." Mark Lee explained before leaning to Hyeop to hug him. "How are you? I missed you man. From now on, call me Mark." he told him.

Lucky kid. His favorite teacher is now his friend.

"So, is the food good in this place?" Sana asked getting all Mark's attention. Why did the kids bring an older girl?

"Good? The food here is awesome." Johnny greeted with a menu and drinks. His eyes widened when he recognized Sana. Yuta's friend from the Yogurt parlour that he would annoy most of the time.

He wrote down their orders, and left immediately to the kitchen, looking for Yuta. He was concentrating on perfecting his wasabi takoyaki for his prank.

"Serve these will you. They're the guests at our kitchen." He said on an ill voice, maybe Yuta would feel sorry for him and take his place for a while.

Taeyong took the order slip and started making takoyaki. Still no response from Yuta.

"Yah! Nakamoto Yuta! You lazy ass son of a b..."

"Fine!" he finally stood up, taking one of his deadly wasabi takoyaki then poked Johnny's side to tickle him and make him gasp, before shoving takoyaki in his mouth.

Johnny winced on the spiciness at first but it surprisingly tastes good.

He watched as Yuta prepare the food one by one. The clueless guy will probably waste all of it as soon as he sees the girl inside the dining room

"Ready to go." Taeyong signaled Yuta. Yuta placed them carefully on one tray, carefully walking towards the dining room. Johnny followed to record Yuta's reaction, because he knew that it would be priceless.

Upon entering the room, his eyes found Sana right away. He turned around with his eyes wide, then caught Johnny filming him.

"I'm going to scoop your eyes off with an udon spoon and make it a takoyaki after this." he threatened making Johnny chuckle. Yuta served the food as fast as he could to avoid Sana.

It was no use because the moment he entered, Sana knew right away that it was him. The annoying customer, noisy and hard to talk to.

"You work here?" she asked with a smirk.

"He owns the place." Hyeop tried to raise his amount as if it was an auction. It's the only chance that this dinner is going to be free.

His cousins sensed right away that something is going on here.

Jihoon, the master of setting up just had to get involved with it. He couldn't sit still unless these two are helplessly falling in love in front of him. "Noona, you're from Osaka right? Our hyung is from Osaka too. It's why he built this restaurant, he missed home so much." Jihoon told Sana.

Yuta hugged the tray, feeling insecure for the first time. He wanted to impress this girl. For the first time, he wanted her to think he's cool.

Taeyong cooked the takoyaki, for sure it came out perfect. She'll love it for sure.

Sana tasted the food and chewed on it so she didn't have to answer Jihoon, or even make a statement.

"Okay, never mind. If I go to Japan where should I go first?" Jihoon asked.

"Hiking!"

"Mountains!" they said simultaneously answered, satisfying Jihoon's plan.

"I'll take note of that. So does everyone in Japan enjoy it? Hiking I mean?" he asked.

Both Yuta and Sana mentioned several spots where Jihoon would enjoy.

"You first have to try Osaka Castle on the first night, or maybe afternoon." Sana was first to tell him.

"Night? Afternoon? Then how can I take a picture of the castle?" Jihoon asked.

"Lots of people go there for street foods, not the castle." Yuta answered instead of Sana. She just sat there nodding her head in approval.

"Why not take a picture?" Jihoon asked.

"Your background is going to be lots of people taking pictures too. What's the point?" Sana answered this time.

"Right!" Yuta agreed until they're both only speaking in Japanese.

Jihoon shrugged then glanced at Hyeop who was about to give him a hug of success. "Dude! They're talking." he was very much impressed at Jihoon's match making skills.

"Little did they know that it was a match made from hell." Baejin narrated, trying to steal away Jihoon's narration spot.

The four of them laughed, enjoying the fact that they ordered the whole menu and it's going to be free. Thanks to Sana.

Was it?

It wasn't.

Only Sana's food was free. The four of them was sent to the kitchen to wash dishes.

"Look at us. He's no longer our teacher but he's still making our lives miserable." Hyeop muttered. This is not what he had in mind when he called Sana.

He glanced at the kitchen where the two still keeps speaking Japanese.

"How's the new History teacher?" Mark Lee came out of nowhere, blocking what Hyeop was staring at earlier.

"H-he's broken hearted. He keeps relating heartbreak in anything." Hyeop was honest on this one.

"Yeah, that sounds like Jooheon." Mark Lee chuckled to himself. "By the way, where's Doyeon? You guys were inseparable." he intrigued so Hyeop won't think about washing dishes too much.

"I'm relieved that I didn't got her into this. There's no way I'm going to make Doyeon wash dishes." he said even though he knew that his cousins are young to roll their eyes on him.

They didn't just roll their eyes but chuckled. Hyeop faced them with a glare, "Laugh at me when you get back to Somi." he roasted Samuel.

"I agree." Jihoon second the motion. He just couldn't stand the way Samuel was treating Somi lately.

Samuel was silent and just tried to wash the dishes faster to keep himself occupied. His cousins were right anyway.

In the middle of washing dishes, Jihoon's phone started ringing. They weren't allowed to answer phones at this time so Mark Lee went to see who's calling.

"Jihoon, your mother's calling." Mark Lee thought it was an exception because his parents might be looking for him. That's right, they're just minor, and they're kept here washing dishes.

Mark was so close to letting them go.

Jihoon wiped his hands to answer the phone. "Umma?" he asked in an impatient voice.

"Where are you? We're already at the airport, we have two hours before the flight back to the US." his mother answered on an undeniably annoyed voice.

So, they're leaving? There's nothing he can do to that then.

"Well? What are you waiting for?" she asked impatiently. So they still wanted to see him before the flight. That's the time they managed to set aside for their son?

Jihoon won't complain though

"What's the fastest vehicle to the airport?" he asked.

"Park Woojin." Kwon Hyeop joked.

The rest of them glanced at each other before considering Keon Hyeop's advice.

There's nothing faster and reachable transportation other than Woojin. With that Jihoon called him and waited in front of the restaurant. The others were left inside, still washing dishes, wishing their parents would call too.

Jihoon's not the type of person to lie and make up stories, but right now, they wanted to have his excuse too.

Samuel wanted to pretend he's sleeping while standing up, but knowing his cousins, they might splash him with filthy water that they used to rinse the plates.

...

Somi and Chungha went to Hotline Bling where Daniel was currently waiting tables. His smile still works with the female customer.

"We should've invited Sejeong." Chungha said snapping her fingers.

"I don't think Daniel's ready for Sejeong." Somi responded. To be honest, she already knew that if Sejeong's here, it'll just be another heart breaking moment for her.

They sat down ordering food. It was Jun who attended on them. For some reason, Daniel was still uncomfortable with Somi, even after she defended him with Sejeong's lost time turner necklace.

"What can I get the pretty ladies?" Junhui asked politely as always.

"The usual." Chungha told him.

He started writing down their usual drinks. "How do you even sleep at night?" Jun asked Chungha. "Chocolate milkshake, double scoop of Chocolate ice cream and one scoop of vanilla." he red Chungha's usual order.

"Girls need their chocolate." it was all Chungha can reply.

Chungha started a conversation about Seongwoo, not even giving Somi a chance to speak. It didn't matter though, because she's only here for one reason.

And it's to confirm if it was really Wonwoo who's finishing the list. He's probably in the kitchen, but how will she find a reason to be in the kitchen.

"Wait, I forgot I wanted fries." Somi told Chungha before shamelessly entering the kitchen. Dokyeom was at the dessert section, making Chungha's milk shake.

"Hey! What can I do for you Somi?" he asked.

"Wonwoo?" she answered unsure.

Dokyeom smiled, turning around. "Wonwoo! Another visitor." he called out.

Another?

"That's two girls in one week." Seungcheol muttered, then stopped talking when he realized that it was Somi. Something's up.

Wonwoo removed his apron, giving it to Vernon. "Watch over him." he told Mingyu before going straight to Somi. He looks exhausted on from grilling burger patties. He even smells like grilled beef.

"Let's talk outside." Somi told him, leading the way at the back of the restaurant.

"I know you know why I asked you to come here." Somi told him, but Wonwoo doesn't have time for guessing game. There's a lot of customers tonight, he needed to get back there as soon as he can.

"Yes, absolutely. I got the stuff but you first need to show me the money." he joked as if they're both dealing with drugs.

"Wonwoo, I'm serious." Somi stomped him feet in frustration. "I know you got the list, and you're trying to finish it." she said.

Wonwoo scratched his head then sighed. "List of what?" he teased.

"You know what I'm talking about." Somi was now getting impatient.

"Don't tell me you're associated with Samuel's revenge list?" Wonwoo asked her but she couldn't answer. He was now speechless now that it is confirmed that kind and innocent Somi also wanted revenge.

"As you know, there's only one number that we haven't accomplished yet." Wonwoo told her.

"Enough of this. How could you? I never meant to go this far. It's why I threw that away in the first place. You saw me on the part, didn't you? I went to Samuel's room, took the list and threw it away. I wanted to get rid of it! But you took it from trash and started doing your own revenge." Somi accused.

"What? What trash?" Wonwoo asked.

"Stop acting clueless. I threw it away. You took it and started finishing all of the unchecked numbers." Somi told him. The two of them are now confused.

"So it was you who threw it away? Soyeon gave it to me." Wonwoo told Somi but who would believe him? Soyeon was innocent.

It was even her who said that Wonwoo has the list, and she's right. All these years, all the information she had from Soyeon was reliable.

Wonwoo's got to be lying.

"Soyeon told me that Samuel dropped something, and it was the list." Wonwoo explained.

"It can't be, would you stop lying to me!" Somi demanded.

Wonwoo bit his lips,
