You and Daiki have been friends since kindergarten. He is always cold to anyone. When you were in kindergarten, you got bullied, and he saved you.

Even now, you guys are still friends. He is always smoking, and you always kept telling him to stop, but he didn't.

One time, you caught him smoking. You stole the cig and threw it at the ground. He got angry and pinned you to the wall. You thought he would hurt you, but then he kissed you aggressively. "Then I'll take on what's mine."
