An over-age corporate slave, suffering from the torment of a paranoid mother urging her to marry, accidentally encounters a cold and aloof doctor, who turns out to be a deep, hidden invisible big shot. The two live together by fate, gradually developing feelings and settling their hearts. The family of origin constantly exerts pressure and suppression, and hidden plots lurk within the workplace. The scheming big shot transforms into a wife-protecting maniac, always standing before her, accompanying her to fight against wind and rain, and joining hands to break through all predicaments, forging a path of survival that belongs to them.
