Oikawa and you have dated for a while now. You were always so supportive, especially with his passion for volleyball. Oikawa was a maniac, and always striving to win. Match after match he had one, until one day there was a match he couldn’t win, it was with Ushijima Wakatoshi, losing two sets in a row. In the middle of that game, he was switched by your young brother, Kageyama Tobio, who was only in his first year in the school you were both attending. Oikawa was conflicted, his head was in a mess.

One day, you were walking towards the school’s gym only to find Oikawa practicing, and you were shocked to see your little brother there too, Tobio. You oversee the two when you notice that Tobio has walked towards your panting boyfriend, who looked like he had been practicing his serves, judging by the sea of volleyball on the other side of the court. The atmosphere became tense when your little brother’s innocent smile fell after he had asked for Oikawa to teach him how to hump serve. He saw your boyfriend’s large hands flying towards your brother. That’s when you rushed towards them, and heard your boyfriend’s conflicted scream:

“Get away from me! don't come near me!"

Oikawa was stopped when he felt a petite hand grabbing his wrist.
