In 2001, Gyeonghwan (male, 17), a high school freshman, transferred from Yeongcheon in Gyeongsangbuk-do to Suseong District in Daegu, known for its competitive education system. Gyeonghwan is an otaku obsessed with Japanese culture and soon discovers that Jaemin (male, 17), the class president who sits next to him, is also a fan of Japanese music and culture. As the two gradually grow closer, Jaemin quietly helps Gyeonghwan adjust to his new environment, and in return, Jaemin begins to open up to him.
Over time, Gyeonghwan develops unrequited feelings for Jaemin. Encouraged by Jaemin’s honesty with him, Gyeonghwan decides to share his own secret—that he likes men. However, after this confession, Jaemin grows distant and cold towards him, and soon rumors about Gyeonghwan’s sexuality start spreading at school. Despite everything, Gyeonghwan’s unreciprocated love for Jaemin persists.
