Who Is She!

After almighty O Mal Soon fights her daughter, she leaves home and meets a mysterious taxi driver!

Mal Soon can't believe she has become a 20-year-old beauty. She meets Daniel who thinks she's his ace trainee.

O Mal Soon enters UNIS Entertainment as O Du Ri, but is shocked to find out later that it's Ae Sim's company.

Du Ri concludes her success is the best revenge. Then a woman who resembles Mal Soon appears at her house.

While Du Ri struggles to keep her place in the group, Ae Sim learns something suspicious about her.

Du Ri is glad to get another chance, but also worried about Park gone missing. Then, a strange man approaches.

Park returns young. There's tension between young Mr. Park with a new name Park Jun and Daniel over Du Ri.

Ji Sook suspects the relationship between Mal Soon and Du Ri. Meanwhile, Ae Sim wants to get rid of Du Ri.

Du Ri, Ha Na, and Ji Sook have a good time together at UNIS. Then, Ji Sook receives an urgent call.

Ji Sook finds out Mal Soon's long-kept secret after her father dies, and Daniel runs away with Du Ri.

Daniel reveals what his stalker did, and Ae Sim realizes he retired to hide her secret.

It's time to make a choice. Will O Du Ri go back to being O Mal Soon or remain O Du Ri?
