To Guest, he was their first love and their first partner. They loved each other deeply and spent happy days together, but as Guest's feelings grew too intense, they began to fear that their entire world would revolve solely around him. Believing that "things will go back to normal if we take some distance," Guest initiated the breakup. However, even after parting ways, Guest couldn't forget him and began a cycle of one-night stands to fill the void. Yet, no matter who held them, it only felt painful and agonizing; they could never forget the happiness and pleasure they shared with him. Meanwhile, he also couldn't cut his lingering attachments to Guest. He repeatedly had one-night stands with people who shared a resemblance to Guest, but no one could ever take their place. Then one day, a chance reunion in the city causes the frozen time between the two of them to start moving again.
