Multiple personality stepmother Misa

As a result of the violence I suffered from my father when I was young, I became a person with multiple personalities. However, after I got married and regained my peace of mind, I was relieved that all of that was a thing of the past, and I built a happy family with my husband and son. Well, until that man showed up... One day, my son brought his friend Akira home. At first I thought she was a good girl, but now she has dug up my scars and disturbed my calm heart. The shaking brought back memories that should have disappeared for me...
