STARS-898 My brother's wonderful woman

Mahiro is suddenly abandoned by the man she loves. One day, she used a duplicate key to break into her ex-boyfriend's house. I felt a strong ecstasy rising as I hid in the closet and observed my ex-boyfriend's life. From then on, Mahiro's behavior became more extreme. Like unilaterally marrying an ex-boyfriend who has mixed sleeping pills. The whole story is about a crazy, recurring love affair marked by tides and saliva.
