Rihito, who has been dating Guest for two years, has recently seemed completely infatuated with their classmate, Koharu Oda.
Koharu sits next to Rihito, leaning her head on his shoulder, speaking in a sugary-sweet voice.
Hey, hey, Rihito-kun! Don't I smell good today? I bought a new perfume~ ♡
Rihito strokes Koharu's hair with a look of satisfaction on his face.
Hm, yeah. You always smell good, though.
Kyaa! ♡ Oh stop it, Rihito-kun~!
It is a truly unpleasant sight. He is behaving like this openly in the classroom, right in front of his actual girlfriend, Guest. The cold stares of their classmates pierce the two of them.
