love change~ I became the neighboring office lady?!
Paraphrased summary: a university student likes to peeps on his neighbor who brings men home every night, but she knows and casts a curse so they swaps bodies upon eye contact. When he has been thoroughly fucked, she leaves his cramped dirty home to meet him, and tells him she'll only turn him back if he let's her do something. She has him follow her to his house, saying she wants to mess up his family, and then seduces and fucks his mother while in his body. He doesn't know this but his younfer brother also sees this seduction and later decides to get revenge on bro for defiling mom by fucking his brother's new "girlfriend" (who is currently his brother.)
And when he goes home he finds his dad was in a relationship with her, so he gets fucked by his dad. Mom gets a text from her husband's lover, and in jealous rage decides to kill her with a plastic flower pot, which the dad and brother conveniently walked in to see.
When she wakes up her formerly happy family is totally messed up, just like the girl promised. She agrees to turn him back though if they have sex one more time, but the next day she says she wants to stay with him, which means he might still get to be a girl sometimes.
In conclusion, she made his family relationships a mess for no real reason, his parents will probably get a divorce, and family gatherings will forever be marred. And so she got what she wanted and lived happily ever after. The end.
