i really like this anime but the end is illogical -so like what happens to Treize did he married Lillia? -did they won with that dancing competition? -how is he alive didn’t he fall down with the train? -what was his parents’ reaction when they know that he is alive? -didn’t he show her his sister Merielle? -and what about Wilhelm what happened to him? -he didn’t say the truth to his daughter? -dose he stays like that to the end he hides his truth or his real personality? -and that blonde girl that works with Wilhelm didn’t she kill him because that he killed her dad? -and Lillia told Treize that there are many questions I want to ask you ... did she ask him? - what are the questions? - and the princes that they were protecting her what happened to her? -And the one who takes Lillia what happens to him .. he died or what? please if someone knows telll me im dying to knoww please
