I watched years ago and I don’t remember the cast. It was about an young man who was responsible to kill a girl or several girls, I guess? And a girl, who was abused, goes after him. When he tries to kill her, she says something that remais she wants to die and then he give up. I remember one part he was disguted by her demostranting sad emotions and, in the end, she kills herself and he cried for her.
