A completely different take from the original plot, instead of developing romantic feelings for each other, Miki and Yuu have become somewhat close to a real brother and sister relationship. Also, Yuu meets another one of Miki's friend and falls helplessly in love with her because of her kindness and gentle nature. AU: It's completely okay if you don't like that I've split Miki and Yuu apart because I like them as a couple as well but there's still that tiny little thing in my head that keeps whispering that even if they aren't biologically related, their siblings now and that's all that matters.
