The daughter of announcer-turned-host Oh Sang-jin and Kim So-young went to elementary school for the first time. On March 4th, Kim So-young posted a photo on her social media account with the caption, "All dressed up for the first day of school." The photo showed their daughter Sua leaving the house for her first day of school. Sua caught attention wearing a lace skirt and a large, fancy ribbon in her hair.

When a netizen commented, "Why is Sua so cute going to school all dressed up?" Kim So-young replied, "I feel like her princess days are almost over, so I decided to enjoy it too. Let her have fun as much as she wants." When asked if she cried upon going to school, Kim So-young said, "She looked excited and nervous. She's all grown up now!" expressing her proud feelings toward her daughter.

Kim So-young is currently pregnant with her second child and, in her late pregnancy, shared her thoughts, saying, "There are so many things to do as a parent..." The day before, she fulfilled her role as a parent by putting name stickers on each of her daughter's school supplies. Kim So-young's dedication has touched many people.

After leaving MBC in 2017, Kim So-young launched and has been running her own personal brand. Last November, she boasted record-high sales performance. Oh Sang-jin and Kim So-young married in 2017 and have a daughter; they are currently expecting their second child. This couple positively influences many by balancing family life and professional achievements.
