Y/n was engaged by her childhood friend, Eren. She kept this secret from her due to Carla's request, to only tell him about this arrangement when he's at an specific age. But Y/n doubt the feelings will be mutual, because Eren is still in love with their other childhood friend, Mikasa who is away for a meantime. She didn't gave the courage to tell Eren about it, the fear of rejection was holding her back. But because of her care, she didn't realize that.. the man was slowly falling in love with her. It was his ego that was holding him back, because he promised to himself that he will only love Mikasa and no one else. Not until.. the first love came back, unexpectedly.. Eren made a huge mistake that drives the situation in a mess.. his anger on seeing his own best friend Armin, kissing Y/n without knowing the whole reason. That's the start of the problem, a lot of misunderstanding and painful event that took place.. nobody expected it to end this way.. no one expect Mikasa forcing Eren to choose her over Y/n.. And no one was expecting that this tragedy will take someone's life.. and drive Y/n to her own darkness. TW: death, mental disorder, vulgar words, smuts, suicide.
