Sweet Romance: The Cold CEO Cries in My Arms

All she wants is a simple, sincere relationship. If someone promises to love her, she can give him her whole life. But after giving everything she has, why is she rewarded with a breakup? Fine! If it's over, it's over! Things have already come to this, and after shedding a couple of tears, she puts it behind her. But why, at such an unlucky time, does she have to meet someone who brings her even more misfortune? He clearly doesn't look like a good person, so why does she end up carrying him home when she has no other choice? She kindly saves him and brings him home, and he takes her house away from her. She hates him, but she has nowhere else to go. In the end, after the two of them negotiate, they settle on an agreement that isn't exactly official. She never expected that a mere agreement would make her fall completely for him. She's baffled too. She knows perfectly well that he's no good, so why has she fallen for him anyway...?
