Realizing his attraction to Hinata, Kageyama avoids contact with him outside of practice, but Hinata won't accept not being friends off the court -- especially when Kagayama is off his game. In an effort to get his reason across and satisfy his own feelings, Kageyama holds him for a few minutes on the premise that Hinata isn't allowed to ask why. But instead of scaring Hinata away, it's the start of a daily ritual he allows to improve Kagayama's performance that only inflames unrequited love.
Original comment: I've never seen this show but I've read about these two hooking up like ten times now.
