The crazy romance drama is about a man who pretends to have amnesia when he is told he will be murdered and a woman who pretends to be his fiancée when she is told she doesn’t have much time to live. Noh Go Jin is the CEO of GOTOP and the top math instructor in the country. Lee Shin Ah is Noh Go Jin’s secretary with zero presence. She is at the top of the company when it comes to sincerity and responsibility, but she is so quiet, introverted, and hopeless at bragging that she seems non-existent.
