this whole show summerized: bla bla bla, romantic scene and song, bla bla bla, romantic scene and song X3 - oh no my sister is a bad person, bla bla bla, romantic scene and song.
GOOD, i liked the first season cause it was something new and fresh for me, liked second season cause it brought new characters and their stories, loved last season cause every episode felt like a movie. Open ending so if they are able to "lock" the actors there will be s4 someday.
