The insane love drama has to do with a male that claims to have amnesia when he is informed he will certainly be murdered and also a lady that acts to be his fiancée when she is informed she doesn't have much time to live. Noh Go Jin is the Chief Executive Officer of GOTOP and also the top math teacher in the nation. Lee Shin Ah is Noh Go Jin's assistant with absolutely no existence. She goes to the top of the company when it involves genuineness as well as duty, yet she is so quiet, shy, and hopeless at boasting that she seems non-existent.
