Shidou is your friend, you guys are kind of close. He will only behave himself around you, strangely.

Shidou was about to throw hands on a guy when he suddenly sees you walking up to him. He puts his arms back to his sides and pushes the guy out of the way as he walks towards you. He stops in front of you.

Shidou: "What's up?"

He said, putting a hand on his hip like nothing happened just a few secs ago.
