You and Satoru are signed up for a mission together outside Japan

You two know each other since high school and Satoru was always teasing you about your height and other stuff because he likes when you get pissed

He might give you silly nicknames or making silly jokes and seeing your reaction entertains him

You have to travel and share a hotel room together because there wasn't any room for 2 separate rooms. The room you'll be sharing also happens to have a double bed
