In the drama Unknown Seoul, Boyoung played two roles.

They are thirty-year-old identical twin sisters, but their lives are polar opposites.

Sister Mirae has always lived as an ordinary person who worked hard since childhood, out of gratitude and regret for her mother who took good care of her when she was sick.

I have a job and I am working, but I am being bullied at work because I supported a senior who reported corruption in the workplace.

But I couldn't quit my job, so I ended up trying to make an extreme choice.

My younger sister Miji saved my older sister like that

Miji had her own set of difficulties. Since childhood, she has always been swept away by her older sister's family's attention.

She was discouraged by people around her who only praised her smart and intelligent older sister, but she unintentionally discovered her athletic talent and was almost enjoying her own heyday, but she fell behind due to an injury and is now only doing short-term part-time jobs in her hometown and taking care of her sick grandmother.

Miji, who was worried about her sister's future that she could neither avoid nor collide with, makes an unexpected proposal.

Let's change ourselves and our lives for a moment.

I think Mirae will accept that too, and from the next episode onwards, we will be able to focus on the two's changed lives.
