Mi Ryu is a high schooler with a gorgeous yet childish mother and seemingly terrible luck in life. Her mother is remarrying (again) to a rich man to pay off her stack of debts and get them out of their impoverished life.
With the debt erased and a new set of family members, Mi Ryu finds herself in a predicament. She believes she is becoming attracted to her twin stepbrothers, but is unsure whom she likes more: the sweeter Ha Neul or the stubborn Ba Da? On top of that, she has the vicious class vice president as her stepsister. A girl can’t catch a break!
