Adopted by the Lu family, Chi Jiyue grew up with her three foster brothers. The two families agreed she would marry one of them on her 22nd birthday. But the nanny’s daughter Lin Ruoyu drove a wedge between them, turning the once-close siblings into foes. Diagnosed with late-stage gastric cancer, Chi chose euthanasia to bid her final farewell—only to be rejected by the three brothers. They even gave her wedding dress to Lin, forced her to give up her mother’s grave, and held Lin’s groom-selecting wedding on the original date. On that very day, Chi ended her life, leaving the brothers utterly devastated.
