This one has some serious Beauty and the Beast vibes. You have one guy who fell in love with a girl, but when she lost her life a mystic put a curse on him to live for 100 years where he would suffer great pain until he could find her reincarnated and she would have to be the one to feed him the magic potion to lift the curse and they could then live their rest of their lives together. As time is running out, he meets a boy and believes that is the girlfriend reincarnated. At first he's repulsed by the idea, but in time he changes his mind and they get together. However, not long after that a woman shows up who might really be the reincarnated girlfriend. I won't give spoilers to what happens, it is a good story with romance, magic/mystical themes with action and adventure. It is not really a comedy, although there are some mildly humorous parts. As for the ending, some have a very happy ending and for some not so much as they don't make it to the ending. Spoiler: the only thing that I didn't like: this series is about 10 hours in total and it is entirely based on the question, 'who is the real girlfriend' and then they blow the ending and they end it in such a way that the viewer doesn't learn who is the 'real girlfriend'. That was extremely annoying and disappointing, so while you get a good story, you never get a complete story and you don't know any more on the last episode than you did on the first.
