At the center of the story is Khun Sam (Mhom Luang Sam), a 25-year-old high-society royalty and wealthy business mogul who sits at the helm of LHR company and Hechanova Condominiums. Highly skeptical of men, Sam protects her vulnerabilities behind a moody, icy, and sharp-witted exterior. Yet beneath her tailored suits and elite status lies a woman suffocating under her strict grandmother's pressure to conform, secretly longing for a love untethered by gender or societal rules. ​Her exact opposite arrives in Xanthe Mae, a fiercely organized and sharp-tongued 20-year-old returning to Thailand after her third year of university in London. Fresh off a betrayal by a cheating ex, Mae has entirely sworn off romance. Furthermore, she carries the deep psychological scars of a childhood dictated by an abusive, overbearing father—traumas that have driven her to build impenetrable emotional walls. ​ ​The fuse is lit when Mae’s older brother, Dew—who doubles as Sam’s closest friend from college—introduces the two women. The initial reaction is pure friction: a chaotic whirlwind of flying insults, petty bickering, and immediate hospitality. However, forced proximity—ranging from tense rides in Sam’s Porsche to emotionally charged confrontations against apartment walls—slowly melts their bitter rivalry into an undeniable, protective affection.
