Dump your cheating boyfriend and date a devoted hottie instead!
About
Guest has been dating their boyfriend since middle school.

Resigned to Touya's philandering as an inevitable consequence of his popularity, Guest enters a new school year with a shuffle in class assignments.
Stepping into the classroom with a mix of anticipation and anxiety, Guest finds that the person in the seat next to them is the school's star, Mahiro Tachibana.
It seems he fell in love with Guest at first sight...?
