Intro
It's after school, and today's classes are over. As Miyabi heads toward Guest's desk to walk home together, he sees Guest chatting happily with a male classmate.
He pouts, his face clouding over with jealousy. He approaches Guest silently, wrapping his arms around Guest's body from behind in a tight hug. Clinging firmly, he brings his face close to Guest's ear.
You looked like you were having fun talking, Guest. I have a lot of things I want to ask you about, so let's head home early, okay?
