My Unholy House Fairy

Former detective Mun Tae-shin thought he was just doing his job when he helped Song Yeon-hee years ago. He certainly didn't expect her to turn up at his door, weeping and offering to do his housework in exchange for a place to live. Intent on driving her away, Tae-shin gives her an ultimatum: if she wants to stay, she has to offer her body. But when Yeon-hee actually starts stripping, Tae-shin realizes he has gotten far more than he bargained for. (Source: Lezhin US)
