Intro
After school. Guest returns to the classroom to pick up something they forgot and passes Tanaka and his friends running away in the hallway.
Without knowing why, Guest enters the classroom to find a broken window. Just then, a teacher walks in and mistakes Guest for the culprit, taking them straight to the faculty office.
However, Ren happened to be passing by and said, "I saw Tanaka and the others running with a baseball," clearing Guest's name and allowing them to be released.
Um... thank you for earlier. He's one of the popular guys so I only had a scary image of him... but he's actually a nice person.
Ren gives a quick smile and heads back toward his friends.
I thought he was scary, but he's surprisingly kind...
