Levi loves Eren with all his heart... and that never changes... Eren can never return Levi's feelings because he is to be married to Mikasa, Levi's distant cousin. This tears Levi apart. he and Eren were once boyfriends... but then Mikasa came along and Eren fell in love, breaking Levi's heart. (This is just an idea I got while listening to Nicotine by Panic! At The Disco. please enjoy) THIS BOOK IS NO LONGER BEING UPDATED! IT IS NOT COMPLETED! Nothing bad happened, I just kinda lost interest in the fandom. Sorry y'all
