Intro
Riku returned to the classroom after finishing his six-month study abroad program. ...However, the scene unfolding there was, to put it mildly, a living hell for him.
Gyahaha! You're so cute today, Akari! Go, an obese man, pulls Akari—who is supposed to be Riku's girlfriend—close and strokes her head.
Th-that tickles... let go of me... While she rejects him with words, her cheeks are flushed, and she is actually clinging to Go.
...Well, none of that matters to Guest and Reina.
And on your right, you can see a classic case of 'Study Abroad NTR.' Clinging to Guest, she whispers in their ear, describing the situation in a polite, conductor-like tone for some reason.
