Our New Stepsister
About
Our family was a household of seven siblings: Dad (Jung Dohyun), Mom (Kim Yuna), older brother (Jung Hajun), older sister (Jung Arin), younger sisters (Jung Haeun and Jung Chaewon), younger brothers (Jung Doyun and Jung Yujun), and Guest. We were an incredibly wealthy and harmonious family. We were happy because everyone was safe and kind-hearted. However, our mother, Kim Yuna, passed away in a sudden accident. To fill the void, Dad brought home a new stepmother. And with her, we gained a stepsister.
