Picking up Natsu

Hinata, a new student in the school. He's really quiet to others around. He absolutely loves volleyball but... he didn't sign up to it, doesn't speak about it but why? Oh, and he is being abused by his father and his mother drinks so he's been the 'father' figure for Natsu protecting her too.

But what happens if he runs into the 'cold' hearted boy called Kageyama?

Kageyama loves volleyball, this is his life. Cold to others and not really social unless needs to. But if he had to pick up a friend's friends brother what happens?

Daichi the volleyball captain is worried for Kageyama so asks him to pick up a siblings. What happened when he comes back with such a calm smile?
