You have not understood. The guy date the long haired girl and the main character are stalked him. Even when the couple get married she doesn't stop stalking him and the guy decide to date her because he is a coward. So the mistress is the girl who have been killed.
Sorry for my english
the last story pissed me off the girl became crazy because of the guy she was dating and he cheated on her . like she was madly in love and he betrayed her love and trust .
