Yoon Ju-won

Gender: Female Age: 28 Occupation: Owner of Daldal Bakery Positive and bright personality She is an optimist who forgets today's bad events by tomorrow. She has to speak whatever is overflowing in her heart immediately, and to her, the dinner menu the family shares at the table is more important than grand life plans. New family members appeared for Ju-won. Her father, the police officer Dae-wook who lives upstairs, Dae-wook's son San-ha, and Hae-jun, whom her father brought home to raise—these five have spent 10 years together. Though their surnames are different and they don't share a drop of blood, she has never once thought they weren't family.

Kim San-ha

Gender: Male Age: 29 Blunt but sweet toward Yoon Ju-won He may look cold on the outside, but he has a warm heart that truly cares for Yoon Ju-won and Kang Hae-jun, who grew up like family. As an orthopedic resident at Myeongju University Hospital, he is envied by those around him for his intelligence and looks. Though he appears to be a perfect person with nothing lacking, he is a 'tsundere' character with deep inner scars and guilt. Occupation: Orthopedic Resident at Myeongju University Hospital He has been mature and thoughtful since childhood. Even in difficult times, he swallows his pain alone, telling himself "it'll be better after a night's sleep."

Kang Hae-jun

Gender: Male Age: 29 Speaks in dialect Occupation: (Former) Basketball player (Current) Unemployed? Naturally bright. He is like a crisp, white T-shirt freshly dried in the sun. After his mother Seo-hyeon left him at his aunt's house, he followed Jeong-jae—a man his mother had met on a blind date only once—and took up a room in Oryun Mansion. For the next 10 years, he lived like Jeong-jae's biological son and Ju-won's biological brother. He enjoyed basketball, which he started with Jeong-jae. He felt even more proud when people said he was good at it just like his father.

Park Dal

Gender: Female Age: 29 Occupation: Lawyer Trait: Ju-won's friend She lived diligently as a model student just as her mother wanted. She graduated from the university her mother longed for and became a lawyer by attending law school as her mother wished. She figured she had done enough for her mother by becoming a lawyer. So, she decided to live her life her own way, following her heart. Leaving her mother in Seoul, she moved back to Haedong alone and opened a law office. Her peaceful daily life was short-lived when she came face-to-face with her high school first love, Hae-jun, as he walked out of the house right across from hers.
