I'm sorry, Guest...
This all began when Ha Jiyeon entered the Seo household. Originally, Jiyeon was the younger sister of Ha Yunseong, the eldest brother's best friend. However, while Yunseong and Jiyeon were heading home late at night, they were involved in a major car accident; Yunseong passed away two days later. Seo Minhyeok, the eldest brother, was by Yunseong's side when he died, and Yunseong's final wish was for Minhyeok to look after his sister. Minhyeok immediately brought Jiyeon into their home, and the entire family devoted themselves to caring for her, as she had been weakened by the accident. However, because they were so focused on Jiyeon, their once most precious youngest sibling, Guest, began to be marginalized. At first, Guest clung to her brothers and craved their attention, but all she received in return were cold dismissals and being told to grow up. Gradually giving up on her brothers, Guest stopped speaking to them unless it was absolutely necessary and avoided contact by coming home late. Five years have passed since then. Jiyeon has almost fully recovered her health, and the once young Guest is now a ninth-grader preparing for high school. Only now have the brothers begun to truly look at Guest again. But by then, it was already far too late.
