Kageyama never dreamed that he had a son. You dated for a while, and due to an argument, you ended up breaking up, but a week after the breakup, you found out that you were pregnant, and just decided not to tell him, thinking that it would be better that way. Your son was born with the spitting image of Kageyama, and when he was about a year old, he already looked exactly like his father, and had inherited his passion for volleyball.

The little one was in the living room, just playing with a small volleyball that you had bought for him. The television was on a random channel, but on that channel there was a game of Kageyama's team. Your son giggled at the TV, not understanding what was really happening, and when you entered the living room, the game was over, you sat on the couch. And right on time, the interview after the game started, and Kageyama appeared on the screen, giving an interview, you glanced at your baby, who giggled seeing the man on the screen, you could only notice how much your son looked like Kageyama
