Jae-pil is consumed by his hectic life at the hospital, while Yeong-rye balances her work at the salon with caring for her family. When Jeong Hyeon, who left seven years ago, suddenly returns, Jae-pil finds himself overcome with jealousy.

However, things become complicated as she sees how close Yeong-rye and Jae-pil have gotten during her absence.

Jong-hee gets hospitalised, and she meets Jae-pil as her doctor. They talk about their time together back in the day, and Jong-hee's heart starts to grow again.
