Soon-shin goes to Mi-ryung’s house for acting lessons and is surprised to see her. Yi-jung also comes there. Mi-ryung scolds her for coming late and tells her to clean the kitchen. Mi-ryung asks Soon-shin about the reason for becoming an actor. She answers that it’s for money. Mi-ryung finds it interesting.
Mom is still sad about doubting dad. Soon-shin comes home and tells her about going to Mi-ryung’s house due to work.
Joon-ho’s mom complains to dad about Mi-tryung treating Yi-jung badly and making her work. Dad is happy to hear that.
Yoo-shin thinks about what Chan-woo said about liking her. She meets Hye-shin and Woo-joo at the shop and asks Hye-shin about her husband and if there is any problem. She doesn’t tell her anything.
Joon-ho asks Mi-ryung what she thinks about Soon-shin. She tells him that she has no aim of becoming an actress, but she is fresh and adorable.
In-sung tells Joon-ho that Soon-shin is very ordinary looking and that she should have a plastic surgery.
Joon-ho takes Soon-shin to his dad’s clinic for taking suggestion on plastic surgery. She refuses. He tries to make her understand its need. There, Yoo-shin has also come for her appointment and sees Chan-woo there. She tells him to forget about love and only be friends with her. This whole conversation is heard by Soon-shin as well as Joon-ho. She is heartbroken and he understands the whole situation.
He tells her that she is plain and nothing compared to that girl. If she will go inside the clinic, she will become so pretty that many guys far better than Chan-woo will come after her. She says that he wants to make her a top star but does he know only plastic surgery. He becomes angry and tells her that she has no confidence, no passion, no conviction and thats why she couldn’t gain the love of the man she likes. She is in tears and says that if she becomes pretty, will the plain person inside her be gone.
Yoo-shin tells Soon-shin that she and Chan-woo are only friends. She also knows that Soon-shin likes him. She sees her script and shouts at her that she is doing the same stuff again that caused dad’s accident. Now, Soon-shin cannot take anymore and answers back that why is it her fault and why she treats her like this. She tried to become perfect like her, but she did not succeed. Yoo-shin is taken aback.
Joon-ho feels bad about what he said and calls Soon-shin, but she disconnects her phone. Next day, at restaurant, she ignores him.
Yoo-shin takes Chan-woo to the bakery shop for a talk. She tells him that Soon-shin likes him and he is surprised to hear this. The man there, Jin Wook again thinks that he is cheating with his wife. He also sees Hye-shin coming there and tries to stop her from coming into the shop. Chan-woo and Yoo-shin also come out and the whole misunderstanding is solved.
At home, Yoo-shin again asks about all this to Hye-shin and she finally tells her about her divorce, the reason being the extra marital affair of her husband. She asks her not to tell mom about this.
Mi-ryung asks Soon-shin about her family. She tells her that her father passed away and she is the youngest daughter among three. Also that she is worthless. Mi-ryung tells her that she should not think like this about herself and that “the only person who can change your life is you.”
Yi-jung goes to her dad’s clinic where she sees Chan-woo, but he doesn’t recognize her.
Joon-ho finally comes to Soon-shin’s house with flowers. There he meets her whole family, Soon-shin tells them that he is her manager. Also, that he likes her, but they don’t have any relationship. Soon-shin drags Joon-ho out of the house with her.
Outside, when Soon-shin and Joon-ho are talking about her acting, mom listens everything. They finally tell her about it, but mom refuses to allow Soon-shin to act as they already suffered many hardships due to that fantasy.
Next day, Soon-shin comes to Joon-ho’s office to resign. He asks if she won’t regret this. She simply goes and is very disappointed. She thinks a lot and finally runs somewhere.
Chan-woo’s dad is in deep thinking and he goes to Mi-ryung’s place where he looks at her house. He hides when he sees her coming and also he sees Soon-shin going inside that house.
Soon-shin tells Mi-ryung that she has decided to quit but she wants to ask her something. She knows that she praised her exaggeratedly in front of Yi-jung. But does Mi-ryung really think that she has talent. Mi-ryung replies: yes. Soon-shin smiles and is extremely happy to hear this.
