Love behind bars (Ereri)

Eren is a very nice guy, he's kind and caring and is very trust worthy but all that could change when Eren is sent to court for supposedly stabbing 15 people at a mall. The thing is he doesn't remember doing it at all. But that doesn't matter because he is still found guilty and is sent to prison for life.
As soon as he gets in prison he sees that the atmosphere is filled with violence. But one person is different and he seems to come into a liking of this person.

Will Eren survive prison life and did Eren really stab those people?
