A psychiatrist with relationship issues looks forward to meeting a handsome, charismatic author whose novels she admires, but she's soon disappointed.

When Jang Jae-yeol's new novel comes out, he learns that his plagiarizing ex also released a book, and she's suing him. Ji Hae-soo is surprised by a visitor.

When Hae-soo kicks Jae-yeol out of the house, he prepares a lavish good-bye breakfast. Jo Dong-min and Park Soo-gwang also risk getting expelled.

Hae-soo rushes out of Jae-yeol's apartment after spending the night. While retrieving her cell phone later, she sees him at work -- in a new light.

Hae-soo loses her temper when Jae-yeol returns home with Oh So-nyeo, who spends the night, but she still allows him to accompany her to a concert.

Jae-yeol starts to open up to Hae-soo, but after their kiss, she avoids him, thinking that it was just a whim -- until he asks her to date him.

Jae-yeol shows Hae-soo his caring side as he prepares breakfast for her before she leaves for the hospital and plans a trip for the two of them.

Hae-soo agrees to a spontaneous trip with Jae-yeol, but they start off on the wrong foot. Will an injured arm and petty quarrels ruin their night?

Hae-soo expresses her affection for Jae-yeol while he is writing, which leads to a fight. Soo-gwang reveals his long-held feelings for So-nyeo.

Hae-soo is surprised and hurt when Jae-yeol says he is moving out; Yang Tae-yong finds Jae-yeol's wallet and sees something that shakes him to the core.

After a fight, Jae-yeol shows his anger at Hae-soo on the air, and she responds in kind; Tae-yong asks Jae-yeol to make a call under false pretenses.

Hae-soo realizes Jae-yeol's persistent marriage proposals are serious and confides in Dong-min, who finally confronts Jae-yeol about Han Kang-woo.

Hae-soo learns of Jae-yeol’s mental disorder and Kang-woo's existence. When she talks to Jae-yeol, he tells her that he thinks Kang-woo will soon die.

Hae-soo tries to get Jae-yeol forcibly hospitalized and spends one last heartbreaking night with him. Jae-yeol gets a final call from Kang-woo.

Jae-yeol and Kang-woo -- and Hae-soo -- stay at the hospital, but Hae-soo can only watch Jae-yeol from a distance, tormented that she cannot help him.

Aware of Jae-yeol's disorder, Hae-soo's mother and sister try to intervene. Jae-yeol urges Hae-soo to leave him and go to Okinawa for a year.
