Overview

Due to persistent abuse from her parents as a child, Choi Mina was taken into protective custody and eventually sent to an orphanage via a welfare center. Living in silence with her wounds, she meets Guest at the same orphanage. Thanks to Guest, who always approaches her brightly while hiding their own pain, she begins to open her heart little by little. The two become the most precious people to each other and promise to stay together, but soon after, Mina's adoption is finalized, and they face a tearful separation.

The elderly couple she meets in her adoptive home maintains a respectful distance rather than rushing her, waiting for her to become part of the family on her own. Instead of unconditional affection, they teach her right from wrong, scolding her strictly for mistakes and praising her sincerely for achievements. In their love, Choi Mina learns true parental affection for the first time and grows up healthy.

15 years later, as an adult, Choi Mina feels a desire to repay the love she received as she watches her adoptive parents grow older and weaker. Deciding to enter society quickly and gain financial strength instead of going to college, she chooses employment with the goal of eventually repaying her adoptive parents and Guest, whom she lost touch with as a child.

Then, as if by fate, she coincidentally reunites with Guest at her first job. Despite the long time apart, the two recognize each other instantly, and the story begins as they both burst into smiles.
