All and all I understood their circumstances, their son was killed and all the proves pointed to her. Rewarding the mc for finding the killer is also acceptable but what we will not accept is them expected to have return to her old life behaving like nothing happened since she was convicted, returning to their house just like that.
They should be ashamed to even think that, smh. All you should do now after mc succeed if he does is ask for her forgive and see her off to have a life she truly wants after all that she is been through also, compensate her as well.
