I Liebe them together! I would hate it just a bit if Ninako ended up with Ren, I mean come on, he actually "erased" her from his herz and tried to block out his feelings, whereas Andou has only ever been honest about his feelings
This is dedicated to every couple, Liebhaber all over the world. Just imagine how lucky Du are to have your better part Weiter to you. :3 Be happy together forever.
