Author's note: this is gonna be in the time skip where Kageyama and the others are older.
Kageyama's POV
I walked towards my house where my girlfriend is, the practice of Japanese National Team is hard as usual. My girlfriend's name is (Y/N) Iwaizumi, apparently she's Iwaizumi-san's younger sister, she's 17 years old now.....I know I am older by three years but who cares? It's only three years gap, but anyways she was born (Month/Day) 1999, I was born on December 22 1996. She is in Aoba Johsai High School, where her older brother goes to when he and Oikawa-san is in high school. She has a chubby form and is shy around people she just met, but she was really a fan of me since she saw me, that is when she is still in junior high, she studied at Yukigaoka Junior High. She is so sweet when we are just two, Iwaizumi-san didn't mind that I dated his younger sister, we are just careful.
"Sweetie, welcome home. (Y/N)-chan is waiting inside you're room"my mom said as I thanked her and yawn, I walked to my room and saw (Y/N) laying in my bed, with my hoodie again. She always do this.....steal my hoodie and just cover herself up. It's kinda cute. Like usual, she always brings me a whole box of milk and yogurt from Coach Keishin Ukai.
"As usual, you bought me so many.....wonder what crazy mind do you have, idiot"I said as she stirred up a bit in her sleep as my heart beats fast, I blushed and walked away trying myself to calm down. I took a bath and changed my clothes to my casual clothes like in the house.
"Hmm.....Tobio? Ohayo"she said as I look at her
"Ohayo, did you get a good sleep?"I asked as she smiled and nodded while patting the two boxes in my nightstand.
"I bought this for you!"she said as she lounge herself to me, she's sooooo soft and cuddly, that is why like her.....she keeps me warm in the winter and stuff. Even though I hate to admit it very much, she still has a way to find me a blushing mess and do what I can't do outside the room.
"You are crazy to even buy those two boxes every time you visit my house. What are you? An Idiot?"I said as she smiled and I hugged her back, she placed her soft hands on my hands that was on her waist.
"I am you're Idiot, anyways, Sugawara-san said that you also are an Idiot when you're in high school! You failed an exam!"(Y/N) said as I froze, she keeps in touch with Sugawara-san because she was her teacher when she was in elementary
"I-I didn't failed!"I said as she laughed at how I stuttered, she's not shy anymore because she's so comfortable with me
"Yes you did! He said that you and another guy failed English!"she said as I shut her up by kissing her on the lips. Of course my long hands got her chin and just tilted her head and kissed her....
"Why so sudden Tobio?!"(Y/N) asked as I licked my lips
"You're very noisy so I had to shut you up of course, anyways why are you wearing my hoodie again?"I asked as she blushed and pouted
(Y/N)'s POV
I thought he wouldn't notice.....guess there is no point on lying.
"I was cold, I came here from school and we'll, it's our Christmas Party so of course I wore the dress your mom gave me for my birthday"I said as I took off the hoodie and shivered at the cold because the cold hit my skin, it was pink and fitted, my curves showed a lot.

"What do you think Tobio?"I asked as I looked at my stomach and I realized he hasn't answered yet
"Tobio? You okay-----gwaaa! Tobio you're nose is bleeding!"I said as he covered it and look away, I saw his whole face was very red, as if he's a little tomato....
"I-I-I'm fine! Just take off that dress to my bathroom, changed into this instead"he said as he quickly fumbled his clothes while I chuckled
"Neh, neh~ do I really look sexy in this outfit?"I asked, I wanna tease him for a bit, he then gulped
"Y-yes......now c-c-change!"he said as he shoved his clothes on me, I smiled and nodded
"Oh yeah, boys said that I look hot and sexy in my classroom earlier~"I said and walked towards his bathroom, as soon as I touched the door, he spun around and kissed me passionately. We kissed until we both lost air
"Change. Now"he said as I nodded
"Okay Ou~sa~ma~!"I said as I walked inside his bathroom. I got out and he suddenly hugged me from behind, didn't even noticed him there.
"Tobio? What are you doing?"I asked as he growled like an animal
"Do not. Do not show too much skin too others, especially your private areas. You are only mine and mine only!"Tobio said as I sensed that he is jealous.
"Of course I am yours, who would wante? You know boys only complimented me"I said as he kissed my cheek
"I know, but I hate that! No boys will be looking at you with those eyes!"he said as I smiled and ruffled his hair.
3rd Person's POV
(Y/N) and Kageyama was asleep on the bed and his mom took pictures and posted it on her social media.
"You two are very cute!"Kageyama's mother said as she squealed outside of Kageyama's room. Everybody saw it, including the fans of Kageyama. Everybody doesn't know that he already had a relationship, and then the next few weeks, Kageyama didn't look through his social accounts because it's private though (Y/N) was different, classmates of hers supported her relationship with the famous setter of the Japanese National Team, all of Kageyama's fans accepted it even if they were hurt. It was the Japanese National Team's interview and the reporter was asking each member.
"So this question is for Tobio Kageyama. We know that a picture is roaming around all over the world, please show it"the reporter said as Kageyama was confused until he saw the picture, he was trying to remain calm and collected but worry was written on his eyes
"The question is, is she you're girlfriend?"the reporter asked as Kageyama can't lie on this interview because it is serious in the first place.
"Yes. She is"Kageyama said as the reporter smiled
"I heard that she is the younger sister of the former ace of Aoba Johsai five years ago, Hajime Iwaizumi and the childhood friend of Aoba Johsai's famous Setter, Tooru Oikawa. Well you all heard Mr. Kageyama, (Y/N) Iwaizumi is the girlfriend of Tobio Kageyama. Thank you for answering my questions, and Mr. Kageyama? Is there anything you want to say to your girlfriend and your fans?"the reporter asked as Kageyama nods
"If anyone disrespected her, you will die. And I-I love you (Y/N), don't forget that you idiot!"Kageyama said as the reporter smiled.
