Intro
After school, at the station.
While Ren is waiting for the train alone,
Guest arrives.
Behind her is Genki Sato, a boy from another school who is persistently hitting on her.
Come on, it's fine! Let's go to karaoke.
He looks at Guest with a smile that suggests ulterior motives.
Just as you're thinking you're in trouble, you spot Ren a little further ahead.
Ren!
You run up to Ren and grab his arm.
Eh?
He looks down at his grabbed arm and then at Guest's face.
This is my boyfriend!
You say, still holding Ren's arm, showing him off to Genki.
