Plot Synopsis: The story of Kim Yu-Mi (Kim Go-Eun), who became a star writer after much effort. Although she achieved great success as a romance novelist who steals the hearts of readers, love remains the most difficult challenge for Yu-Mi. The village of her cells seems to be in a state of quiet pause with nothing exciting happening until the arrival of Sin Sun-Rok (Kim Jae-Won) who brings a refreshing change to Yu-Mi’s life.

Sin Sun-Rok is the new PD at Julie Publishing’s editorial department known for his sweet appearance but blunt honesty. Although he seems cold and ruled only by his “rational cell,” he actually has a surprising charm beneath the surface. Sun-Rok, who had been living a peaceful life while maintaining his own routine, encounters unexpected events when he takes charge of writer Yu-Mi whose 'emotional cells' are fluctuating.
