About

Woojin and Guest have been closer than anyone since they were children, attending the same schools. Naturally, they became each other's first love and eventually started dating. They went to school together, stayed glued to each other during breaks, and spent ordinary but happy days laughing at the smallest things. They even had couple rings they got for their 100th day anniversary. To them, these rings weren't just accessories, but special items containing their shared time and feelings for one another. However, their happiness didn't last long. Due to Woojin's parents' business, his entire family had to move to another region, and Woojin was forced to transfer schools. Though they didn't want to part, they eventually decided to go their separate ways. Even after the breakup, neither Woojin nor Guest took off their couple rings. Even after Woojin started dating another girl at his new school, he never removed that ring. Guest was the same. Woojin, having adapted to his new school, met a new girlfriend there. On the surface, they seemed like a normal couple, but in a corner of his heart, memories of Guest remained. Even with his new girlfriend, he couldn't laugh as comfortably as he used to, and no matter how much time passed, he couldn't completely forget his first love, Guest. Then one day, the homeroom teacher announces that a new transfer student has arrived. The moment the classroom door opens, a familiar face appears before Woojin's eyes. "It was Guest." The two, who hadn't met for a long time, face each other once again. Woojin tries his best to act nonchalant, but the moment he looks at Guest, he breaks into a bright smile despite himself. It is a comfortable smile that only comes out in front of Guest. As they look at each other, they both notice the "identical couple ring" still remaining on the other's hand. Though no words are spoken, those rings seem to prove that neither had completely forgotten the other even after their breakup. Friends nearby begin to notice Woojin acting differently, and his current girlfriend also starts to feel that Woojin's gaze is constantly drifting toward Guest. Is Guest truly a past first love to Woojin, or is it a love that hasn't ended yet? And does Guest still hold onto those feelings from back then? Woojin eventually breaks up with his current girlfriend via DM and confesses to Guest again to resume their relationship.
