"Okay sweethearts. Mama is gonna apply to some agencies today, and you two are gonna behave and be nice to your Grandma. She's gonna take care of you two while Mama is working as a pro hero!" Y/n explained to the two. Katsuya started tearing up while Katsurin smiled.

"M-mama! Please be safe and come home early!" Katsuya sobbed.

"Don't worry mama! I'll protect Grandma and Katsuya!" Katsurin proudly declared.

"I'm sure you will, dear. You're strong and I know you will keep them safe. Be nice, okay? I'll buy you two some gifts later if you behave!" Y/n patted their heads. She walked towards the door, Inko following her.

"Mom, please be safe. Thank you so much for taking care of the kids." Y/n said with gratitude.

"It's nothing, dear! I enjoy spending time with kids, especially my grandkids. Makes me remember when I used to take care of you and Izuku." Inko smiled.

"I'll be back later, please text me if anything happens!" Y/n opened the door and waved.

"Bye mama!"

"Love you mama!!"

"Bye 'Tsuya, 'Tsurin! Behave, okay?!"

Y/n arrived at the tall building, the words TDRK Agency in bold letters displayed at the entrance. She sighed, gripped her suitcase where her hero costume was stored, and her bag where her files were.

She was instructed to go to the highest floor where the pro hero, the owner of the agency, stayed for a couple of hours in his free time. The pro hero was said to be very busy, and she was just lucky enough to have at least 30 minutes of his time on his very busy day.

She just wished that he was nice and not so cold-hearted.

Izuku did say that he was someone that she used to know.

Y/n hated it when he was right.

"Enter." The person from inside the office said. His voice was awfully familiar, only a bit deeper.

"Good morning, sir. I was recommended by the pro hero Deku--"

"Y/n Midoriya?"

"Shoto?!!!"

After their graduation party, Y/n decided to lay low after that incident. She couldn't just start working as an intern to some pro hero or even be a sidekick after being well aware that she could be carrying a child.

Y/n immediately went to All Might for a talk. She asked for his help to get her to America, where she impulsively decided to stay and raise her kid. Well, kids.

After that, for 5 years, no one has ever heard from Y/n or the strong Flarean who was well known in her high school years. No one knew about her whereabouts except Izuku and their mother. In their first year in UA, Y/n was known to be one of the hero in training who contributed to defeating so many villains back when the war against the League of Villains took over.

It broke Shoto when he found out that she was gone. His mind grasped the hope that she was still alive somewhere. He spent months and years searching for her, but nothing.

And now that she's back, right in front of him, he was never letting her go again like that.Shoto shot up from his seat and ran towards the girl. He was scared that he was just dreaming, but after feeling her soft and warm skin, he figured that he wasn't.

"Y/n? Are you really Y/n?"

"Shoto! Yes, it's me!" She giggled and broke away from the hug.

"5 years.. You were gone for 5 years..." He trailed off.

"I know.. And I'm sorry for leaving so suddenly, without saying anything to you." Y/n placed her hand on Shoto's cheek, gently caressing it. Shoto leaned into the touch, feeling her warm skin against his.

"Wait.. You're the one applying to my agency? Is that why you're back?" Shoto asked.

"Yeah, I really need the job. It's been years and I may be out of practice, but I'm willing to learn all over again." Y/n sheepishly said.

"You're hired. You're in. I don't care. You're gonna start working as my sidekick and then you'll rebuild your name as Flarean again. And then you'll be a pro hero. Just like you dreamt."

"I appreciate it, Shoto." Y/n smiled.

"Well, let's get going. I'm only doing patrols for the rest of the week, but I do have a mission starting the week after. Are you up for it?" Shoto said with a challenging smile.

"Are you kidding? Let's kick some villain asses!"

-

"Flarean! Make sure the citizens are safe!"

"Got it!" Y/n rushed towards the cowering people at the corner. She knelt beside the injured woman and started treating her wounds using a first aid kit from a nearby table.

As soon as she was done, an explosion from behind her erupted. The front door was in complete flames, the only way out.

"Flarean!" Shoto shouted from outside. He was about to use his ice to stop the fire when another exploded.

"No!" Y/n shouted back, and they were all forced to move backward, away from the fire. There was no way Shoto could control the fire now.

Her only motive is to save the trapped people inside the building.Maybe it was time for her to use her quirk.

Y/n jumped towards the fire. Her hands reached out in front of her, and she moved them apart, the large fire that was about to engulf the entire building moving along the direction of her hands. She raised her arms and pulled them back to her face, sucking in a deep breath, the fire being sucked into her mouth.

"Flarean! " Shoto called as soon as he saw the clearing. The fire soon dissipated, and Y/n rushed back to help the citizens evacuate before debris fell on them.

As soon as everyone was out, the crowd cheered and cameras flashed before the two heroes. Ambulances awaited them and some rescuers helped the injured people. The villains that caused the explosions and hostage have been arrested after they were free from Shoto's ice.

"Pro hero Shoto! May we know your new sidekick?!"

"That costume! I know her, she was an intern from past hero agencies!"

"She was a student in U.A! But why is she back now?"

"Everyone! Please give us some space. No interviews. My sidekick may not be comfortable answering questions." Shoto shouted, shielding Y/n away from the pres.

"Flarean, am I right? Why did you disappear for 5 years and came back as a sidekick for Number 3 hero Shoto?" A mic was shoved into Y/n's face.

"I--I had to l-leave Japan because something came up.." Y/n answered.

"Flarean!! Are you planning on staying as a sidekick of pro hero Shoto or are you going after becoming a pro hero?!"

"Definitely a Pro hero... And I-I'll be up in the top 10 in no time!" Y/n stuttered, but she was definitely confident in her answer.

The crowd was getting rough, so Shoto grabbed Y/n and pushed their way out.
