Art curator Sung Duk-mi is passionate about her work -- and her secret hobby. At an auction, she enters a bidding race against famous artist Ryan Gold.

When Ryan becomes her new boss, Duk-mi is concerned about the changes he brings to the museum -- and that he might recognize her from the airport.

A meeting at a special collector's home leads to trouble for Duk-mi, who finds herself swept up in noisy rumors.

To save the exhibition, Ryan and Deok Mi attempt to persuade Choi Da In, a visual art director, to work with Cha Shi An so he can participate. However, while helping to convince her, Da In finds out Ryan and Deok Mi's relationship is fake. Later, Da In tells Deok Mi that Ryan wants to end the fake relationship and that she likes him.

Ryan figures out Duk-mi's secret, and decides to have some fun with it. To the delight of the museum staff, Si-an comes for a visit.

Deok Mi can't leave her teary man alone and invites him to stay the night at her house. The lucky Lion gets to spend the whole night with Deok Mi, and Da In and Eun Gi get closer by sharing their feelings through a drunk conversation. Meanwhile, the painting by Lee Sol gets restored, and Ryan shares with Deok Mi what Lee Sol's paintings signify to him.

Ryan has an idea for a way to get Duk-mi out of the scandal, to Nam Eun-gi's displeasure. Cha Si-an has an unfortunate run-in with a fan.

The museum's new intern poses a problem for Duk-mi. Si-an agrees to join an exhibition. Ryan sets out to procure a photographer's final work.

Duk-mi's parents invite Ryan over for an impromptu dinner. Sindy and Duk-mi both win spots at Si-an's fan event.

Ryan is shocked when he hears Deok Mi say that she wants to end their fake relationship. Although the words "end it" came out of her mouth, Deok Mi can't ignore the feelings she has for Ryan. At the end of finishing off an awkward day of feeling out each other's true feelings, Deok Mi can't fall asleep. When she goes online to chat, she meets "Latte" who comes knocking with a similar situation to share.

Ryan finally tells Deok Mi how feels about her, and asks her to be in a relationship for real. Deok Mi and Ryan spend happy days together but Eun Gi, who has no idea about their relationship, plans to confess his feeling towards Deok Mi. Meanwhile, Seon Joo gets furious after watching her husband’s show regarding fangirling.

It’s Deok Mi’s birthday and Ryan makes it very special for her. When the day couldn’t get any better, Deok Mi learns the truth about the boy, Yoon Jae, and also realizes that she had been the only one who was living in the dark. When she comes around to understanding everything, she realizes how much the people around her mean to her once again.

"When did you find out that I was Shi An is My Life?" When Ryan confesses the fact that he knew she was Shi An is My Life all along, Deok Mi is appalled. On top of that, Eun Gi who is defending Deok Mi, confesses that he has feelings for her! The sparks of anger begin to fly for the first time as a couple, and to end their quarrel, Ryan takes Deok Mi away to somewhere unexpected. Meanwhile, another battle wages on between Seon Joo and Seung Min.

Ryan finally gets to meet his biological mother. However, the 26 years of being separated don't make it easy for a passionate reunion. Moreover, the words she speaks differ from his memories, making it even harder for him to understand. It's not until he discovers the hidden truth behind her soap bubble paintings that turns him around. Meanwhile, Deok Mi prepares a special event for Ryan.

Deok Mi and Ryan start to sum up all the clues regarding artist Lee Sol's identity. And as they get closer to the truth, Deok Mi sees how frustrated, confused, and painful it is for Ryan. She stays by his side to console him but also gives him the space he needs. Meanwhile, Shi An's mother tries to dissuade her son from going ahead with the exhibition.

Deok Mi looks at Ryan’s paintings and feels like she’s holding back his career that should be blossoming more in New York where he’s from. She’s in a dilemma as she loves her job but at the same time, she’d like to cheer for her boyfriend’s dream. What choice will Deok Mi make?
