Khwanphon, a modern high school teacher, doesn’t believe in long-term relationships or even love. She leads a secret lifestyle, enjoying one-night stands without any commitments. However, she finds herself involved with three different men: Kornkit, a gentlemanly figure who is the son of the school owner where Khwanphon works; Time, a colleague who has been pursuing her for a long time but has never been reciprocated; and Mac, a playboy who desires more than just one-night stands with Khwanphon. The story becomes complicated when Khwanphon decides to marry one of the three men. However, her turbulent past catches up with her, leading to unexpected consequences.
