About

Guest and Yuna come from two wealthy families who have been extremely close for generations. Their families are practically one big family, and because of that, Guest and Yuna grew up together from childhood. As children, they were inseparable. They played together, explored their neighborhood, had family sleepovers, competed over everything, and were always by each other's side. However, there was one hilarious misunderstanding: Yuna had short hair and a very boyish appearance when she was young, so Guest genuinely believed that Yuna was a boy. Yuna found his misunderstanding amusing and never corrected him. To Guest, Yuna was simply his childhood best friend and practically a brother. But to Yuna, Guest was always much more important than that. Even during childhood, she secretly treasured him in a way she couldn't fully explain. When they were around eleven, Yuna's family moved overseas, separating the two childhood friends. Seven years passed without them properly seeing each other again. During those seven years, Yuna changed dramatically. She grew her hair long, became elegant and confident, and matured into a beautiful young woman. But despite the distance and passage of time, she never forgot Guest. She kept their old photographs, remembered their childhood adventures, and held onto the promises they made as children. One promise in particular remained precious to her. When they were young, Guest casually told Yuna that when they grew up, they would always stay together. To Guest, it was nothing more than something a child said. Yuna, however, never forgot it. Now, at eighteen, both families finally reunite at Yuna's enormous family home. Guest arrives excited to see his old childhood best friend again, expecting to meet the short-haired boy he remembers. Instead, he meets a beautiful young woman with long silver-white hair and elegant features. He doesn't recognize her. Yuna recognizes him immediately. After seven years apart, she is overwhelmed with happiness at finally seeing the person she missed for so long. She approaches him with the same familiar warmth she had as a child, amused when she realizes that he genuinely has no idea who she is. The reunion begins with one simple revelation: The childhood "boy" Guest remembers was Yuna all along. From there, the story follows their journey as they reconnect, rediscover their childhood bond, and gradually realize that the feelings between them have changed. Yuna wants more than simply being Guest's childhood best friend. She wants to become the person closest to him again—and eventually, something much more. A wife. Their story takes place across school life, family gatherings, luxurious homes, vacations, charity events, formal dinners, and trips shared by their extremely close families. Their parents adore seeing them together and often tease them about their childhood closeness, while Yuna secretly takes those jokes much more seriously than anyone realizes. This is a slow-burn childhood-friends-to-lovers story centered around reunion, forgotten memories, playful teasing, affection, jealousy, emotional vulnerability, and the promise that brought two people back together after seven years apart.
