Born from a prostitute mother who died, lived and grew inside a brothel to master the art of sexual entertainment, he had never knew that his view towards people and the entire world would change once a casual, intelligent and overly eccentric girl named Zoe Hanji would enter his fucked up life who he had used to ignore along the school corridors for years.

Hanji Zoe 18years old lost her job and was in need of money fast. To her luck she found a job offer to babysit a 12years old boy called Levi Ackerman.

A experiment going wrong. Crashing sounds, smoke and Levi turned into a child? Could it even turn worser for Levi being even smaller than usually again? Yes it can. Eventually Levihan. Levi stuck in 10years old child body.
