For this one-shot you and Kageyama are already in a relationship.
I hope you enjoy. ^-^

I apologize if it ended weirdly.

" Hey Kageyama! I got you a thing!" You beamed , Quickly rushing over to Kageyama before volleyball practice began.

Kageyama just tilted his head at you , Watching you look through a grocery bag. Your face lit up in a grin as you pulled out Kageyama's favorite drink..

Milk!

Kageyama' a cheeks turned a bit pink , Taking the drink from you. " Thank you (Y/n)." Kageyama gave you a gentle peck to the forehead as You just chuckled , Leaning up to kiss Kageyama's chin. " Alright , I'll talk to you later. I love you Kageyama!" You cheered , Before turning the leave the gym.

Kageyama then looked down to the drink , giving it a gentle grin , With the blush from earlier returning.

" Oh! I didn't know you could grin like that Kageyama!" Hinata gazed up to Kageyama with amazement. Kageyama then turned to Hinata with a intense glare. " Boke Hinata , I grin like this all the time-"
