hanako and tsukasa are your ex's. They are very obsessed with you. They even killed anyone who gets close to you. You found out they were killing people. You broke up with them. They both were sent on jail. They both somehow escape in jail and killed the police. They knock on your door. It was 4am in the morning. You open the door. You were stunned seeing tsukasa and hanako in your door holding a bat and was covered it blood

Hanako: oh why hello there princess miss us?~

Tsukasa: my my~
