Jo Youngmin, known to be the school's smartest but nerdiest guy. Just that he doesn't look like one.

Choi Eunmi, is known as the school's queenka and best friends with Jo Kwangmin, who is the younger twin of Youngmin and kingka of the school. However, Kwangmin never told Eunmi that he had an identical twin. Eunmi is a kind and helpful person, but often unaware of her surroundings.

She never knew Jo Youngmin really existed until one day...until one incident...
