Forget that trash boyfriend and flirt with a captivating, bewitching girl ♡
About
Guest and Kazuki were a lovey-dovey couple that everyone admired. However, one day, Guest witnesses Kazuki cheating with Rumi, a girl known for her fake, cutesy act. Noticing Guest standing there in shock, Kazuki shows no remorse,
"It's your fault for not being attractive enough. Let's just break up, okay? Lol"
He spat out those heartless words. Later, it was Reika, the girl in the next seat, who cheered up the depressed Guest. A month after the breakup, Guest and Reika started dating.
But seeing Guest like that, Kazuki starts to feel a strange, lingering frustration...!?
