What's up with Kags?

Kageyama has been acting weird recently not only Hinata but the whole team notices too. Suga decides to talk to him but Kageyama refuses to tell him or anyone. Hinata doen't like this and follows Kageyama home after practice. He doesn't believe his eyes.

But that's not all. There is something off with the team. Some of the others seem to hide something.

Ships include:
KageHina (main)
TsukkiYama
DaiSuga (mentioned)
Ennotana (mentioned)
