Eren Yeager is a 16 year old boy with a destructive mind. Sure, we can all get like that some times, but when it becomes too much it gets dangerous. Eren has lived in a 'mental asylum' for over a year now because of his self destructive mind and haunting dreams and has managed to somehow make every therapist that had attempted to help him run away in fear. The thing is, when Eren wakes up he can barely remember anything of the dream. Everyone just becomes a blur. A new therapist comes along with a suspiciously familiar face and Eren has to decide where and when he has seen this man before. Because of this, he makes sure not to scare away this man so he can work out why he feels such strong emotions towards him. Could it be possible he is actually someone Eren had known for years before?
