Kyou kara Omae no Tsuma wa Ore no Mono ~Irekawatte Taninzuma ni Yaritai Houdai~

Kazuma Hasebe is stuck in a dead-end life, juggling multiple jobs just to survive. After a bad gambling day, he runs into Nao, the 'hot girl' from his school days, who doesn't remember him and openly shows disgust. Her fiancé Takauji joins in the abuse, pushing Kazuma to become a stalker. One day, while spying on Nao's apartment, Kazuma fights with Takauji and they tumble down stairs. Nao rushes out to help Takauji, but something is off—their bodies have swapped! Takauji tries to explain, but now he's the one who's a freak in Nao's eyes. Seizing the chance, Kazuma pretends to be Takauji. With a new body and life, his hell turns to paradise. But how will his love-hate relationship with Nao shape his choices? And how long will this body swap last?
