This is a Snail Maiden?!

Summary

"I can do well... so please.... Can't you let me live here?" Taeshin, a detective, was visited by a girl he had helped out of pity, who came to repay his kindness. As she cried and clung to him, saying she would even do housework, Taeshin deliberately tried to scare her away. "I don't need a woman to do housework. I only need one thing." "What...?" "A woman who will give her body to me. Do you still want to stay, even like that?" He thought she would have understood by now, but the woman said something unexpected. "I... I can do it. I'll do as you say, Detective!" "Song Yeonhui, if you want to stay here that badly, take off your clothes right now." An absurd 'Snail Maiden' had appeared.
