Kim Young-Ran (Jeon Yeo-been), a bodyguard with a troubled past, has always lived in precarious circumstances. Fate suddenly offers her an unexpected opportunity: to marry, under contract, the dying president of the powerful Gasung Group. In exchange, she must live for 3 months under a false identity, that of Bu Se-Mia young woman from a good background, gentle and loved by all.
Sent to a peaceful village to work as a schoolteacher, she strives to play her role to perfection. The inhabitants, charmed by her kindness, welcome her with open arms. All except one: Jeon Dong-Min (Jung Jin-young), a suspicious single father whose son is in Bu Se-Mi's class. As she tries to protect her cover and escape the lusts of the president's legacy, Kim Young-Ran finds herself caught between lies, burgeoning feelings and secrets she hadn't anticipated.
