Se Gye is back in the spotlight with her return to screen.

Meanwhile, Joo Hwan sees a photo of Do Jae being intimate with a woman he’s never seen before and worriedly goes to Woo Mi.
Do Jae leaves a letter for Se Gye, telling her to hang on and promises her that he’ll return. But Se Gye has no idea that he will be undergoing surgery, one that could actually put his life at risk...
Do Jae is faced with a difficult question - if he is willing to be by the old and wrinkly man’s side, that Se Gye has turned into, for the rest of his life. Do Jae finds himself pondering over this dilemma. Meanwhile, Yu Ri is determined to reveal Se Gye’s secret once and for all, and meets up with Reporter Park.
Even in mourning, Se Gye does her best to give a good performance for her movie shoot. Yu Ri feels suspicious about Se Gye, so she hires a person to dig information on her. Meanwhile, Do Jae organizes a special surprise trip for Se Gye for their romantic get-away.
Se Gye’s mother visits Se Gye’s home without notice when Se Gye has changed into a young boy. During her mother’s stay, Se Gye realizes how much her mother worries and cares about her. In the meantime, Do Jae’s grandfather invites Se Gye to his family gathering without telling Do Jae.
Se Gye and Do Jae start going out as a real couple, but in secret. The public think that they’ve broken up, so they need to figure out a way to best play the “we’re good friends” game. But Se Gye’s bliss is threatened as the dreaded date conflicts with her shooting, which could jeopardize her career.
Se Gye is left absolutely perplexed upon seeing Do Jae’s reaction after their kiss. To make matters worse, Yu Ri feigning innocence really gets on her nerves. Meanwhile, Do Jae hears rumors about Sa Ra and decides to step in as what any older brother would do.
Do Jae and Se Gye admit that they’re in a relationship in front of the press and start to pretend they are a real couple. To convince the public, they go on dates in the public places. Jeong Yeon, who doesn’t know the fact that they date for show, disapproves of their relationship and even sends money to Se Gye to make her break up with his son.
Do Jae tries to come up with an idea of covering up the dating scandal with Se Gye. Sa Ra starts to investigate what is going on between Do Jae and Se Gye. In the meantime, Do Jae’s company holds an event to celebrate the launch of a new route to Khabarovsk and Se Gye is also invited to the event.
Se Gye gets worried as Do Jae saw her changed face. Se Gye tries to check if Do Jae really remembers her, but soon, she realizes that he can’t recognize people’s face. Meanwhile, Do Jae somehow feels like he can recognize Se Gye even though he saw two different faces of hers.
