It was before a match, you, his girlfriend, were encouraging him, but he doesn't look in your eyes. He was looking at your chest. With the rain, your white shirt was wet and transparent, that let appear your bra. You blush and cover your chest.

Suna: Here, take my vest. And wait for what'll happen next...

With this words, he leaves you to go into locker rooms to get ready. You were confused, what does he want to say by this... At the end of the match, he invits you to his place and you accept, you're now on the way, congratulating him for the match. But he doesn't respond you. He just makes you enter his apartment, closes the door, and he pins you to the wall.
