Hyuk is hospitalized with Hepatitis B. While the other patients as well as his own parents keep their distance, nurse Da-eun (Chae Soo-bin) ignores them and willingly takes care of him. As time goes by, Hyuk and Da-eun grow closer with the overworked Da-eun even eating and resting on his hospital bed.
A few days before Hyuk would be discharged from the hospital, Da-eun appears to be distant. The downcast Hyuk returns home. But, being unable to forget Da-eun, he manages to find out her phone number and gives her a call.
She eventually invites him to come over to her house, and he stays the night. In the morning Da-eun wakes up to find that Hyuk replaced the broken lamp in her hallway and prepared breakfast for the two of them. Touched by the gestures, they share a brief kiss.
After a while, Da-eun tells Hyuk that she won tickets to Jeju Island for Christmas, and she invites him to join her. Da-eun buys them matching shoes, which he happily accepts, hell-bent on losing weight.
In the next scene we see a slim Hyuk (Jang Ki-yong)) running in the park wearing the same sneakers. A hard working engineer, he is soon told by his superior that he will be dispatched to a big company in Seoul. This means that there will be a long commute from Incheon to Seoul and that if he does well he might be granted a permanent position at the firm. However, on his first day, he finds out there is another candidate; this means that he would not be guaranteed a permanent position at the end of his contract. The other candidate, Bo-yeong (Krystal Jung), turns out to be very competitive, regularly undermining him to make herself look better in the eyes of their superior.
At a board meeting where the team presents a new bridge design based on a proposal by Bo-yeong, Hyuk points out that there is a critical flaw in the design that would lead to a collapse if the bridge would ever be hit by a tsunami.
A humiliated Bo-yeong is told to fix the problem together with Hyuk. While Hyuk leaves early she works throughout the night without taking a rest. At the start, Hyuk takes pleasure in seeing her suffer, but he eventually takes pity on her, and they end up working together to fix the problem. The two start bonding and they continue working on more projects together.
Meanwhile, some strain is showing on the relationship of Hyuk and Da-eun, with both of them regularly working late and Hyuk becoming increasingly frustrated at having to commute between Incheon and Seoul. He usually comes home tired and shows little interest in Da-eun. One night when he comes home Da-eun complains about him not having fixed the broken light bulb and his refusal to take out the trash. When they start arguing she tells him that she hasn’t had her period, and it turns out that she is expecting his child, which she aborts later on.
Rather than being pleased, it seemed to frustrate Hyuk even more. As he realizes he has feelings for Bo-yeong, he starts to distance himself from her and focuses on Da-eun. However, this eventually starts to impact his work. Bo-yeong confronts him and tells him that both of their performance will suffer. Hyuk agrees to work late, and he starts doing overtime again, leaving Da-eun alone at home.
One evening, Da-eun and Hyuk were seen going out together. Hyuk shows no interest in spending time with Da-eun and continuously complains about the crowd and repeatedly says that he wants to eat and go home. Back in the car Da-eun complains that Hyuk never wants to spend time with her anymore.
Hyuk brushes it off and accidentally calls her his “pretty Bo-yeong”. They get into a big argument in which he denies Da-eun’s claims that he’s cheating on her. He eventually drops her off at their once shared house as he drives off in a fury.
Back in Seoul, Bo-yeong and Hyuk are once again working overtime. With all their time spent together and the gradually growing sexual tension between both of them, Hyuk kisses Bo-yeong. Both of them eventually get romantically involved. After a while, Hyuk becomes restless and appears to be longing for Da-eun again.
When neither Bo-yeong or himself is offered a permanent position by the firm, Hyuk tells Bo-yeong at the firm’s team dinner that he will return to his previous position in Incheon. She in turn tells him that she will study abroad as her old job is also not a permanent contract. In the background the team manager announces that they can win a free Christmas trip to Jeju.
Hyuk hearing this thinks of the Jeju trip he was supposed to go on with Da-eun that Christmas. Coincidentally, their flight was meant to be that very evening. Realizing he still loves Da-eun, he rushes to the airport in a taxi. As he pulls up at the airport, he sees Da-eun standing on the sidewalk in front of the airport building. Jumping out of the taxi, he sees her supposedly waving at him. He runs towards her but bumps into someone and falls over.
The man he ran into turns out to be the Hyuk shown in the first part of the film. The scene is the same one from earlier when Da-eun gave the matching pair of sneakers. It is revealed that the Hyuk from the start of the film is a different Hyuk than the one from the main part of the film.
Both storylines happened simultaneously, and it turns out Da-eun bonded with Hyuk while she felt neglected by her partner Jang-Hyuk and because he did all the things Jang-Hyuk didn’t do, such as fixing the light bulb. Both of them leave on the trip for Jeju while Jang-Hyuk returns to the party in shock. Bo-yeong later reveals to him that she had just won the Christmas trip to Jeju and that they could go together, and, despite his feelings for Da-eun, he tells Bo-yeong he loves her.
