Set me free. Many say twenty years old is the beginning of the new chapter, but not for Da Hee. She was still under her mom's guidance. Da Hee, 20 years old, starts to become defiant. She wants to live as herself, not the daughter of her mom. Just a more step to cross the boundary. Da Hee who just became an adult tries to make her first step further.
