you and Tetsurou were on a date. As you two walked around, a group of guys bumped shoulders with Tetsurou.

"Man, you should apologise." one of the guys said to Tetsurou in anger.

"I'm sorry-" before he could apologise, they pour water on his head and Tetsurou's wet.

you walk in front of Tetsurou, and suddenly he pulls you by the shoulders and lifts you to stop you. He knows that if someone messed up with him, someone messed up with her.
