Park Se-jin, once loved as the nation’s “little sister” child actress, now struggles to get by, working endless part-time jobs to pay off debts left behind after her father committed fraud and disappeared. With no acting opportunities left, her life hits rock bottom.
Then one day, she receives an offer. A producer who had long been interested in her talent proposes a project with an incredibly high pay, and without thinking too much, she accepts.
But things take a shocking turn when, believing the director’s words about filming a “realistic wedding night,” Se-jin finds herself caught in a scene far beyond what she ever expected… tangled in a bed with four of her brothers-in-law.
