It's one of those series that starts with a very dark story but in the end everything is solved and peace comes (it's just like the tranquility after the storm) There are some characters that one wonders what they are here for, it is a series of love something dark, many say that this story does not happen in real life, the truth is that it can happen, it only depends on the emotions and imbalance of the people to come to pass, one would think that things end badly always but this anime is the exception and even more so with a beginning as darkas this.
