## History

Sangwoo is a college student who was placed in a group project with other students, including Jaeyoung. Sangwoo ended up being the only student actively participating in the project, leading him to remove the names of the others from the final presentation. This action prevented them from graduating. His first encounter with Jaeyoung was at an art exhibition, where Jaeyoung mistakenly thought Sangwoo wanted a photo. After learning he was unable to graduate, Jaeyoung attempted to contact Sangwoo, without success.

Later, Sangwoo advertised a position to work on a mobile game, and Jaeyoung agreed to join the project. During their meeting, Jaeyoung arrived late and complimented Sangwoo on his looks. Despite discovering that Jaeyoung was one of the project freeloaders, Sangwoo acknowledged Jaeyoung's skills as a designer and agreed to exchange phone numbers.

Jaeyoung moved into the same apartment complex as Sangwoo, leading to various interactions and conflicts. Jaeyoung routinely annoyed Sangwoo, from bulk buying Sangwoo's favorite drink to taking his seat in class. Despite their rivalry, they ended up having lunch together and were paired for a French exercise. At one point, Jaeyoung scared Sangwoo, leading to Sangwoo dubbing him 'Senior Psycho'.

Their rivalry continued, with Jaeyoung once drawing on Sangwoo's face while he slept. Sangwoo responded by trying to isolate himself from Jaeyoung at school, even placing a wooden panel between them. However, their relationship took a turn when Jaeyoung came to Sangwoo's aid at a bar, defending him from a drunk man. Following this incident, Sangwoo allowed Jaeyoung to use his laptop, during which Jaeyoung complimented Sangwoo on his organized apartment and his appearance without his cap.

Jaeyoung and Sangwoo's relationship further evolved when they created a romantic script together for a French conversation practice. Sangwoo was initially resistant to the idea, but eventually participated. This activity led to deeper discussions about love and relationships. Around this time, Sangwoo also began to browse and screenshot photos from Jaeyoung's Instagram, creating a gallery of Jaeyoung photos.

After a conversation with Jihye, Sangwoo came to understand his feelings for Jaeyoung better. He visited Jaeyoung's new work and asked to work on the game project together, which Jaeyoung initially refused. However, Jaeyoung had a change of heart and agreed to continue the project, causing Sangwoo to smile.

As they worked on the game project, Sangwoo and Jaeyoung grew closer. They had another meeting where Sangwoo praised Jaeyoung's ideas for the game and even patted him on the head. However, their relationship took a dramatic turn when Sangwoo kissed Jaeyoung while trying to wake him up. At a bar, Sangwoo confessed he found Jaeyoung attractive and they shared another kiss. Jaeyoung proposed a two-week trial of dating him, which Sangwoo considered. However, upon learning that Jaeyoung was accepted to work at Dex in France, Sangwoo decided not to ask him out.

Despite the news, Sangwoo encouraged Jaeyoung to go to Dex, even though he felt a bit sad. They met outside their apartments at midnight to celebrate Jaeyoung's birthday, where Jaeyoung revealed that he decided to not go to Dex and instead wanted to continue helping with their project​.
