Kageyama stared hard at his phone, almost burning a hole through it as his teammates took notice of their teammate doing this, him almost looking like he was going to murder his phone.

"You good Kageyama?" Hoshiumi questioned the black haired male.

"Oh uh..yeah.." He quickly glanced at the short white haired male before looking back at his phone.

"Is something the matter?" Ushijima questioned.

Opening his mouth, he hesitated on telling his teammates until deciding that he'll do just that. "I think Y/n is cheating on me" he confessed.

"Probably" Hinata said while the others looked at Kageyama with a surprised look, minus Tsukishima and Yamaguchi who were slightly snickering at Hinata's comment.

Kageyama was now with his old volleyball club as they were all eating out. His teammates of the Schweiden Adlers had reassured him that that probably wasn't the case and Y/n was just busy, but the male couldn't help but think otherwise. Hinata obviously wasn't helping his case either.

"Shut up! At least I have a girlfriend!" Kageyama exclaimed to the orange haired male who had grown over the past years since they've graduated from high school.

Hinata was about to say something until Daichi stopped them. "Okay you two that's enough" he said with a sigh, already feeling the nostalgia of when he was a third year and remembering his two first year teammates always bickering with each other.

Tsukishima snorted a bit, looking at Kageyama "Did you ask if she's cheating on you?" He questioned the male. Kageyama only stayed quiet, making Tsukishima sigh. "You're hopeless honestly" he said.

"Shut up!" He yelled.

"Why don't you call her?" Sugawara suggested, making Kageyama turn his attention to his older friend who only gave him a smile. "Wouldn't hurt right?"

Kageyama slowly nodded and excused himself and got up from the table before leaving his old teammates for a few minutes to go outside and call the love of his life, unaware of his teammates spying and eavesdropping on his soon conversation with his high school sweetheart.

Taking out his phone, he unlocked it and opened his contacts before coming across the name of the person that he loves. Pressing the call button, he pressed the phone against his ear and listened to the ringing of the phone.

Once, twice, thrice, five times the phone rang until Y/n picked up the phone, making him tense up and worry that maybe it was true, but still held onto hope that it wasn't.

"Hello?" She questioned. Her voice sounded tired as Kageyama opened his mouth but no words came out, not even a sound. "Hello?" She said again. Soon, words finally came out of his mouth.

"Hey..." He said, his voice barely a whisper.

"Kageyama?" She questioned, he heard her voice brighten up a bit, making his heart ease up a bit, a small smile starting to appear on his face.

"Yeah" was all he said.

"Hey! How are you? Hopefully you're doing well!" She said happily. "I saw your game last week, good job babe" she complimented. His heart melted a bit, hearing her compliment him which made his cheeks a bit warm in the process.

"Well, obviously I would do good.." He muttered a bit which caused her to giggle a bit. Hearing her cute laugh only warmed his heart even more, hell, it even made him feel butterflies in his stomach. "How are you?" He breathed out.

"I'm good, a bit tired from work but nothing too bad" she replied. There was soon silence between the two, it wasn't awkward but more of a comfortable silence, but Kageyama was slowly becoming tense, readying himself to ask her the question.

"Hey-" before he could finish his sentence she had cut him off.

"Sorry, I better get going. I have stuff to do" she said, her voice now sounding a bit hurried. "Bye Tobio, see you soon love you" she soon hung up, leaving him a bit dumbfounded as he processed what had happened until his brain had caught up that she had hung up on him. His arm holding his phone to his ear soon fell to his side as he could feel his chest tighten.

His teammates glanced at each other with a sympathetic look before heading back to their seats before Kageyama noticed they had gone to eavesdrop on his question. They watched him come back inside as he slowly sat back down, not saying anything.

The table was quiet, no one knowing what to say until Hinata broke the silence. "Why don't you just go see her and ask" he suggested shoving a mouthful of food in his mouth. "That won't hurt either right?" He said now with food stuffed in his mouth.

Kageyama stared at the orange haired male before nodding, seeing that he had a good idea for once during the time that he's known the short male.

Slowly the days went by as he anticipated the day that he was going to confront the h/c haired woman. Stepping out of his car, he stared at the house in front of him before slowly making his way to the door, his whole body feeling tense.

His hand raised up to knock on the door but hesitated, voices whispering things to him but he pushed it away and gently knocked on the door. Standing there patiently, he waited for a while before knocking again. He heard a small crash inside the house and cursing behind the door.

"Sorry, go back to sleep" he heard her voice say which made him become more anxious, making the voices come back.

Continuing to wait, the voices of doubt got louder until he saw the door open, showing Y/n who was obviously smaller compared to him. He saw as her hair was a bit of a mess as well as her clothes. Once seeing her, he had snapped and saw that his vision became blurry making her have a worried expression. Before she could say anything he went to her and hugged her, burying his head into the crook of her neck.

"Come on, lets go inside" she said softly, gently petting his hair. She felt him nod as they pulled away, Kageyama holding onto her hand tightly, seeing that if he would let go she would leave him.

Closing the door, she led him to her living room, not minding his tight grip on her hand. Both of them sitting on the couch she noticed him still crying, sniffling a bit making her slip her hand out of his, making him tense up before she pulled him over to her, falling back onto the couch in the process. Y/n was now laying on her back on the couch with her crying boyfriend on top of her, his head resting on her chest.

She started to rub his back with her hand in small circles. The both of them said nothing, staying silent with only the sound of Kageyama sniffling still. His arms snaked his way around her body which she didn't mind as he heard her steady heartbeat while resting his head on her chest.

"Feeling better?" She questioned, her voice hushed and gentle. He only nodded in response making her hum. "Rough day?" She asked. He only nodded again making her nod this time. She started to run her hand through his hair to soothe him.

Y/n felt him relax more which made her smile a bit. Kageyama moved his head a bit to look at the woman who he calls his girlfriend. "Are you cheating on me?" He questioned quietly. He watched as her eyes widened at his question making him tense a bit as she slightly sat up, making him sit up a bit as well.

"What? No of course not! What makes you say that?" She questioned him.

He hesitated to tell her, scared of what she'll say next. He's never felt this way in his entire life until he met Y/n. She was the only person to ever make him this anxious and scared in his life. It wasn't until he felt a hand on top of his and a small reassuring squeeze, making him look up to see that it was his lovely girlfriend.

She gave him a small reassuring smile which made him open up. He told her everything. From when it started to when he started to have his doubts and not wanting to believe them. While telling her, he saw that she was listening to him the whole time as he vented to her. When he was done he saw as she had a small smile, making him suck in a breath before she leaned in and gave him a soft kiss on the lips and pulling away.

"Tobio, you are the most important person to me. And never in my life did I ever think for a second that I would ever cheat on you. I'm sorry if I made you think that, I just had a lot of stuff to do. Work was keeping me occupied and I had a big responsibility to take care of as well." She told him.

He looked at her with curious eyes. "What do you mean responsibility?" He questioned her. It wasn't long until the both of them heard cries and whimpers which made them turn their heads to the sound as she let out a small chuckle.

"Why don't I show you what I mean" she said with a smile.

He nodded at her response and watched her stand up from the couch and walk to the hallway to her room. She seemed to be talking to someone until she came back, holding something in her arms. His eyes never left her as she sat back down on the couch and set whatever she was talking to on the couch. His eyes leaving her form, he looked down on the couch only to see a puppy.

It yawned a bit before noticing him and watched its tail wag, making its way to him before biting onto his clothing and tried to pull him, growling playfully.

"Since you're a pro volleyball player its become a bit lonely since you seemed busy. And I didn't want to bother you when you had your days off so my friend offered me a puppy. I've been busy because this little guy has been keeping me up late at night always needing to eat." She chuckled softly.

He watched as the puppy continued to mess with his clothes before pulling too hard and flopped backwards. It soon made eye contact with Y/n and quickly got off its back and made its way over to her, making her chuckle and pick them up and play with them. He watched in awe as a small flash came into his mind. He soon pulled her over to him, making her a bit surprised.

"Tobio?" She questioned, seeming a bit flustered seeing that she was sitting on his lap facing her. He rested his forehead on her shoulder before mumbling something inaudible. "Sorry I didn't hear you, what did you say?" She questioned him.

"I said will you start a family with me dumbass!" He exclaimed looking at her, his face red.

Hearing his words she became even more flustered. "Are..are you suggesting that we...get married.." She whispered the last two words to which he nodded in response. She stared at him as he waited for her response. He felt a soft pair of lips kiss his before they quickly left his. "Yes of course!" She exclaimed with a wide smile, laughing a bit.

He looked at her with his eyes shining a bit before he kissed her to which she responded with kissing him back. There was soon whining, making them pull away and look down at the puppy who was looking at them, barking at them. She chuckled and gently kissed the puppy to which they responded with licking her cheek. Kageyama smiled and pulled the both of them close to him, happy to start his new family

Bonus:

It wasn't that long ago when Y/n and Kageyama got married. When Y/n got home she heard her husband seeming to talk to their dog who was now almost fully grown. Quietly closing the door, she took off her shoes and made her way to the living room and watched a scene to which she found amusing.

"Just so you know me and Y/n are married now, so she's fully mine" her husband said to the dog who only stared at him, panting a bit. "I also love her more too" he told the dog. It wasn't long until it licked his face making him stare at it. "I guess we can share her..." He muttered causing Y/n to let out a chuckle making the two look over at her. "How long were you there?" He questioned, slowly becoming flustered.

"Long enough to make a deal with Charlie" she said as their dog whose name was Charlie ran over to her, barking a bit and jumped onto her, making her laugh. She crouched a bit to be at the large dog's eye view and started to pet them. "I missed you too" she said with a smile.

Glancing over at Kageyama he saw him scowling a bit making her chuckle and went over to him and kissed his cheek. "I missed the both of you" she cooed as he looked at her. She smiled at him as he sighed, unable to stay upset with her. The two shared a small kiss on the lips before Charlie barked, causing Y/n to chuckle and give the dog a kiss too, making his tail wag even more.

"I'm glad you two are getting along" she said truthfully. There was only a small grumble and a happy bark for a response to her sentence making her laugh a bit. "Come on you two, lets look for something to eat."
