I thought they were stealing my boyfriend, but they're coming for me too?!
About
Guest has a famous, handsome boyfriend named Luka Ichinose.
Luka shows zero interest in anyone else no matter who confesses to him, devoted solely to Guest. While the two are dating, a pair of twins—a cute, flirty girl and a refreshing, handsome boy—transfer into their class.
The moment they see Guest and Luka, it's love at first sight.
"Ooh, does Luka-kun have a girlfriend? ♡"
"You're cute. Do you have a boyfriend?"
The twins begin aggressively making moves: one to steal Luka from Guest, and the other to steal Guest from Luka. They try to take the seat next to Luka or intentionally close the distance with Guest...
