Jang Man Ok is brought up by her grandfather, who teaches her how to fight at his Taekwondo school. Now an adult, she helps her grandfather run the school. Her grandfather goes away for three months, leaving the running of the Taekwondo hall in his granddaughter’s hands.

She helps him escape from his fans, and he asks for her phone number, promising to repay her for helping him get away. As Jang Man Ok is about to return to the hall with the mannequin, she happens to bump into the second member of Take One: the spoilt Tae Ik... After a series of events, she finds herself working for the two lads as a fashion designer. Both of them fall in love with her and… Who will win the girl’s heart?
