Lucian, a devil--no, not those typical devils you know, he really is a devil, as in, he was from hell. Lucian is an evil who's assigned to take the lives of the people who wants to die and will soon die. He's an evil no one wants to meddle. He's like the mini-Lucifer! But what if... yeah, what ifs of a devil... What if he fell for someone who was supposed to be his next prey? Is it possible? If it is, is it allowed to happen? Uh-oh. What about the hell's rule? Rule 1: Don't love, just fuck. Oh really, what the hell?!
