The drama starts with the scene where Soon Shin and her mother comes to meet the con man who introduced himself as Shin Joon Ho. They go into the restaurant in order to talk to him. Joon Ho also goes there to meet Yun Ah. The con man asks them to sign a contract and Soon Shin will become a superstar under his mentoring. Initially they hesitate but he tells them that he will deposit money into her account as per the contract. Finally, they agree. Soon Shin again meets Joon Ho in front of the restrooms. They again start arguing when he tells her that is she stalking him. She tells him that now her destiny will change.
Joon Ho thinks that Yoon Ah asked to meet him in order to sign a contract with his agency. But she has other plans. She asks him to give Mi Ryung to her as she has also opened her own agency and that she will bear all the cost as per the penalty. He is surprised to hear this.
There is a cute encounter of Yoo Shin and Chan Woo, and it looks like they are good friends knowing each other well.
At home, everyone is surprised after listening Soon Shin’s contract and Dad doesn’t want her to join acting field. But mom assures him that let her do it.
Mi Ryung’s ex secretary goes in search for Soon Shin’s dad when he saw him on the street and finds out where he lives. He tries to blackmail Mi Ryung about it, but she seems undisturbed.
Soon Shin’s dad Lee Chang Hoon is in storeroom and finds one of his old photos where he is standing with Mi Ryung. Clearly they have a past. He asks Soon Shin about acting and she reassures him that she wants to do something in her life so she can make her parents proud, and let her do it.
Mi Ryung and Chang Hoon by chance meet each other during morning walk and recognize each other.
Soon Shin’s friend meets her and tells her that she should reconfirm whether that man is Joon Ho as the kind of description she gave is not what she heard about him (she works in some company having the same kind of work.)
It’s revealed that Joon Ho’s dad Shin Dong Hyuk is a successful cosmetic surgeon and Chan Woo is a doctor working under him.
Soon Shin gets a call from bank that she has taken loan. She reaches there and finally finds out that the man who signed contract with her was actually a swindler, who took money on her name as she gave her details to him. Soon Shin gets shocked and goes to Joon Ho’s company but is not able to meet him. She meets Young Hoon there, who tells her that many more persons have been conned. She files a police complaint. But she is annoyed that she will have to pay back the money.
We come to know that Soon Shin is not Kim Jung Ae’s (her mom) real daughter.
It’s also revealed that the eldest daughter Hye Shin is actually having some problems with her husband.
Soon Shin goes to that same restaurant and waits, hoping that may be that con man will turn up. Finally, she sees him and runs after him. But she gets hit by Joon Ho’s car and that man runs away. She starts crying on the street, much to Joon Ho’s astonishment. At that moment, Yun Ah comes there as he asked her to meet him.
They go into his office. He tells her to join his agency. They can still see Soon Shin, sitting on the road. She tells him that if he can make that girl (Soon Shin) a superstar, she will believe in his ability, and that she will sign a contract with him. He is surprised.
