During his lifetime, Calvin Malcolm was always bullied and humiliated. Therefore, when he died, the god took pity on him and offered him to be reincarnated into a better world.
However, Calvin refused. "I don't want reincarnation, I want revenge."
Therefore, Calvin asked to be revived to the original world, but accompanied by the power of cheats. A power that could allow him to succesfully seduce any girl he met.
Calvin used it to snatch all the women in the life of Dale, his bully. His girlfriend, his first love, even his mum.
But, things can sometimes get out of hand.
"Wait a minute, why did my sister get affected too?"
[Your sister is still a girl, isn't she?]
"This is illegal."
[Adam and Eve are also technically still a pair of siblings. So, I think it's still legal, technically]
"Don't you feel embarrassed when you say that?"
