I প্রণয় 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 হৃদয় and tried to block out his feelings, whereas Andou has only ever been honest about his feelings
This is dedicated to every couple, প্রেমী all over the world. Just imagine how lucky আপনি are to have your better part পরবর্তি to you. :3 Be happy together forever.
