After her older brother is killed in a hit-and-run, Donghui chooses to become a single mom to her nephew Himchan, who was abandoned by his birth mother. Thanks to caring people who lend her a helping hand, Donghui slowly begins to map out her life. Donghui’s long-held dream has been to design beautiful clothes that make people happy. Her life with Himchan is on an even keel when she gets a job as a fixed-term assistant designer. Donghui is excited to work toward her dream of becoming a successful top-rate designer, but then comes someone who can put a wrench into her plan.

Chayeol, the younger son of Inha Fashion’s CEO, is a special hire. He has no interest in taking his job seriously or forging close ties with coworkers. But then he becomes intrigued by Donghui, who perseveres even in the face of insurmountable odds. Spending time with her became comfortable, and he ends up loving her to the point where he starts enjoying work. Donghui thinks it’s ridiculous for her, a single mom, to feel sorry for Chayeol, and tells herself not to think about him. In love with Chayeol is Seungju, the head of the design team. Seungju has known and been in love with Chayeol since college. Donghui thinks they make a fine pair and sets out to help Seungju get together with Chayeol. But what do you know? Chayeol asks Donghui out.

Donghui grows fond of Chayeol too. It turns out, however, that Chayeol was in the car that hit and killed her brother Jaeseok. That car crash is the reason Donghui became a single mom, Himchan lost his parents, and Chayeol developed an anxiety disorder. What really happened on the night of the fateful crash? Who is Himchan’s birth mother that abandoned him? Can Donghui and Chayeol overcome even this challenge and be together?
