This bilingual romantic comedy-drama follows Omega brothers Milo, an inventor, and Noah, a healer, who run a tearoom together. Their father publicly advertises them for marriage and revives a childhood betrothal to Alpha twins Adrian, a chief magistrate, and Ronan, a cavalry general. The brothers flee by night, are caught at a coaching inn, and negotiate terms: keep their shop and careers, refuse marking, control separate funds, and make their own decisions. Royal scrutiny, guild hostility, stolen designs, and a violent conspiracy soon close in. Through crises and daily life, the four move from a marriage of contract toward true partnership.
