Idk why people called him slutty when it's in his line of his work. And his job have history which why he doesn't want to leave his job. Also, at the end of the story, I don't think he gonna have sex with anyone anymore but instead, give his customer some services just like a host club. He doesn't want to be treated as wife staying in a cage. And he probably thinka he doesn't have any talents other than selling his body cuz from his state of mind, he very dumb and silly.
I just hate that ML. He immediately changed his heart after see MC's face! I want him to be in despair until I'm satisfied! ヽ(`Д´)ﾉ
lol ya once he saw MC's face everything changed smh
