The trash that harassed the main cast, the trash that bullied the students, and the trash that ultimately 'steals' the heroines if the player makes the wrong decisions.Why, God, Why!?Will my predecessor's past, a horrific mess, haunt me? Will my father, the King of the Underworld, accept me? Will the characters, now a reality, still hate me?I decided to live a regular life, slowly taking the steps to whitewash my reputation..... With an occasional punch thrown here and there......Wait, why is the original protagonist a complete idiot?
