Hu-young comes back to Korea and goes on a blind date that Joseph set up for him. There, he runs into Hong-ju. Upon hearing Hu-young’s return to Korea, Hye-ji plans a welcome party for him. However, Hong-ju turns up drunk, sharing all sorts of things Hu-young didn’t expect to hear.

Hong-ju turns out to be living downstairs in Hu-young's house, and Hu-young asks his uncle to take him on a tour around Seoul. Hu-young and Hong-ju end up having a date at an amusement park, and they have a fun day together. Meanwhile, Joon-ho, who left Hong-ju three years ago, appeared in front of him, asked to work on a project together.

Hu-young realizes that Hong-ju’s ex is Bang Joon-ho, the writer of “My Avant-Garde Lover.” Hong-ju’s boss tells her to work on a project with Joon-ho. Hong-ju hesitates, but she decides to do it in the end. Hye Ji learns that Hu-young has feelings for Hong-ju. Meanwhile, Hong-ju gets into a car accident.

Hu-young confesses his feelings to Hong-ju, but she pretends she didn’t hear it. Hong-ju insists on going home instead of staying in the hospital, so Hu-young takes her to his place to take care of her. Joon-ho sees Hu-young and Hong-ju together and gets the wrong idea.

Hong-ju is forced to go on a fishing trip with Hu-young, Sang-pil, and Wook. Although it’s awkward for her, she tries to enjoy the trip. Hye-ji and Kyung-taek join later, and Hye-ji tells Hong-ju that she’s not dating Kyung-taek. Meanwhile, Hong-ju is told to work with Joon-ho in his studio for a month.

Hong-ju decides to give Hu-young a shot. Hu-young quits his job to stay in Korea and be with Hong-ju. Hye-ji visits Kyung-taek who fell sick and runs into his mother by coincidence. Meanwhile, Hong-ju’s father calls Jun Ho and tells him to stay away from Hong-ju.

Joon-ho tells Hong-ju why he had to leave her three years ago, but even after hearing the reason, she can’t forgive him for leaving her. Hong-ju meets Hu-young’s mom who tells her to end the relationship. Meanwhile, Hu-young finds out Hong-ju’s new project she’s working on with Joon-ho.

Hu-young’s mother tells Hong-ju to come to the US with Hu-young and live there. After hearing that, Hu-young asks Hong-ju to come with him, but she turns him down. Hu-young doesn’t get to see Hong-ju on the day he leaves for the US, but a surprise awaits him at the airport.
