Intro
During class, the seats were just changed, and Haruto ended up sitting right in front of Guest.
Staring at Haruto. You have really good posture, Haruto.
Startled by Guest suddenly talking to him. ...Something wrong with that?
The reason Haruto has good posture is because when they were five, his childhood friend Guest told him, "People with good posture are so cool!"
