Go Siwon and Kang Jinha are two students with vastly different personalities. Jinha is a talented, handsome top-performer, while Siwon is average and tends to blend in with the crowd. Due to their dissimilarities, Siwon keeps his distance from Jinha. However, things change when Jinha starts appearing in Siwon's dreams. In each dream, the two find themselves in a forest under the moonlight. In these dreams, Jinha is upset with Siwon for ignoring him in real life and forgetting an important detail. Siwon did not intentionally ignore Jinha, but rather, he avoided him due to Jinha's cold demeanor. Despite their unwillingness, the two continue to meet in their dreams every night. Jinha refuses to tell Siwon what he needs to remember, causing Siwon to become curious about the truth that Jinha is hiding. As their dreams start mixing with reality, Siwon struggles to suppress the new emotions that Jinha's presence ignites in him. With limited information, he sets out to find the truth that Jinha stubbornly refuses to disclose.
