Reunion of Angel (2014)

Mai is having an awful day. She just got fired, and suddenly two guys show up claiming to be Angels of Death, saying that she's going to die in seven days. Not only that, but her soul will be destroyed completely, so she can't even be reincarnated. The Angels can't prevent her death, but they want to at least help save her soul. They lend her their supernatural powers so she can help people -- just like a superhero. But can Mai do enough good deeds in the next seven days to change her fate?
