“Cheolsu,” a cute bad boy who can’t hate, who can’t study but only play a joke. He heads home after school, but all that greets me is his mother, who died in cyber stock investment, and the parrot shouting “The fool withdrew”. Even that day, there was an incident of a lifetime for Cheol-soo, who was punishing and playing a joke. “Young-hee” transferred to school, and became a partner!!
