Kuso Onna ni Sachiare

Akiyoshi Sunao’s first love breaks his heart in middle school, leaving him wary of romance. Years later, he develops a crush on a girl in his university film club, just as he seems ready to move on from the past. Then Sunao runs into his ex-girlfriend, who admits she has been undermining him—not alone, but with two other people. The next morning, Sunao wakes up in her body, turning his attempt to leave the past behind into something far more complicated.
