A Heart Loves Only Once

While a man's wife and 2 kids are out of town, his ex-mistress unexpectedly shows up to his house unannounced, and she has demands. She blackmails him with a strange list of humiliating rules as a punishment for leaving her, forcing him into a tense confrontation inside his own children’s bedroom. What begins as a negotiation over the "rules" turns into a game of power, where secrets appear and control keeps shifting. By the end, an uneasy “agreement” is reached, but it’s unclear if this truly ends the chaos or simply marks the beginning.
