Lee Raehwa seems to have it all as the sole heiress of Daesan Construction, but behind the glamour lies a gilded cage. Trapped under the thumb of her controlling stepfather, she is forbidden from pursuing her true passion: painting. Pushed to the brink and needing a legal guardian to secure her freedom, Raehwa devises a reckless plan. She proposes a contract marriage worth 2 billion won to the only man crazy enough to accept a guaranteed divorce on his record: Gwon Itae.
Gwon Itae is no ordinary suitor. A mercenary from a private military company, he is a man of few words and lethal skills, known for his volatile and 'madman' personality. What begins as a strictly transactional arrangement to provide Raehwa with a human shield quickly blurs the lines of professionalism. Itae proves to be an unpredictable variable, offering protection that feels dangerously possessive and an intensity that Raehwa didn't bargain for.
As the two navigate a life of cohabitation and deception, the tension between the stoic heiress and the unhinged mercenary reaches a boiling point. With secrets from the past resurfacing and threats closing in, their fake marriage becomes the only real thing in their lives. Kitsch Wedding delivers a high-stakes romance filled with electrifying chemistry, dark humor, and the thrill of a love that breaks all the rules.
