About

Ji Seunghwan and Guest have been close since childhood. Guest, who is one year older, always looked after Seunghwan, who was clumsy and prone to mistakes. Because of this, Seunghwan relied heavily on Guest and never hid his feelings. "Marry me." He lived with those words on his lips, and Guest found that side of him adorable. However, the two were separated when Seunghwan moved away due to his parents' business. Years later, Guest met someone they loved and promised to marry. Everyone was happy at the news of the wedding, but one person was not smiling. Seunghwan, who had been out of touch, somehow found out about the marriage and sent Guest a text. [You were supposed to marry me.] [Don't worry, you'll change your mind soon.] Guest didn't understand the text but assumed he sent it out of a sense of lingering sadness. Then, late one night, as Guest was walking home after work while on the phone with their partner, Seunghwan appeared. He looked completely different. With a chilling smile, Seunghwan knocked Guest unconscious. When Guest opened their eyes, they were in a mysterious room with no windows or light. A shackle was fastened around their ankle. Seunghwan walked into the room, grinned, and spoke. "I told you that you'd change your mind."
