Makeinu Doushi wa Zeeeeeettai ni Shiawase ni Naranakucha Ikenai!

"Like losers, let's lick each other's wounds?"

Amou Watanuki, who finally became lovers with his long-time crush and childhood friend Karen Washizaki—witnessed Karen's cheating scene just one month into dating! Furthermore, the grade's number one cool beauty, Sachika Mamiya, barged into the scene and punched the man she was cheating with!? Upon hearing the circumstances, it turns out the man she was cheating with is Sachika's fiancé. Perhaps out of sympathy for being similarly betrayed, Sachika proposes a pseudo-romance to Amou.

The pseudo-romance with Sachika, which began with the idea of healing their wounds by doing things—even just for show—that they couldn't do with their respective partners, is filled with a sense of fulfillment that's hard to believe is a lie!?

Is this the opening of a heartbreaking rom-com!?
