Maki confessed his feelings to Katsumi and was met with a negative reaction. Despite being separated for 10 years, they are now reunited. However, instead of the joyous reunion that should have occurred, Maki discovered that Katsumi is now involved in dangerous relationships. It turns out that after being assaulted, Katsumi began engaging in violent sex as a form of self-punishment for hurting Maki unintentionally. In response to these revelations, Maki declares that he will take revenge on Katsumi.
