I Cinta 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 hati, tengah-tengah and tried to block out his feelings, whereas Andou has only ever been honest about his feelings
This is dedicated to every couple, Kekasih all over the world. Just imagine how lucky anda are to have your better part seterusnya to you. :3 Be happy together forever.
