The author mistreated the FC by putting her in an abusive relationship that she couldn't run away from. Later she encounters a good guy (that we almost don't know anything about), then the author rushed the story by ending it with a cliffhanger where she needs to choose between the abusive and the good guy.
If you want an ending that leaves you saying wtf (in a negative way) this had so much potential but the author refused to see it
the story is basically not worth reading. the girl is abused by the guy and cant fight back at all. but they ended up together. thankfully the art is good.
