Her Hospital Bed (Sad Eremika Story)

A teenage girl named Mikasa Ackerman got into a bad car crash when she was 15, which led to her having a broken leg, fractured ribs, and the worst of all....amnesia. She doesn't remember her parents who died in the accident, not even her closest friends.

But one day Eren Jaeger volunteered to help some of the patients in the hospital, and when he meets Mikasa they become friends...or possibly more than that.
But there's something that Mikasa isn't telling Eren....what could it be?
