Debuting for 10 years, with two consecutive year-end awards.
The undisputed representative female solo artist of South Korea, Baek Nokha.

Just when she thought she was about to have another award-winning moment, her life takes a turn for the worse with the sudden news of her mother’s passing.

“Do you want to save your mother?”

Before the grieving Nokha, a mysterious cotton puff appears. The cotton puff claims that if she accepts its offer, her mother will be brought back to life.

“I don’t know what the offer is, but I’ll accept it.”

In a desperate attempt to return to her peak moment, Nokha agrees to the contract with the cotton puff. Afterward, she wakes up in someone else’s body.

[Congratulations!
You have become ‘Yoon Cheong.’]

One year after debuting,
Two years after disbanding a failed girl group.

As a member of ‘Steel Blue,’ ‘Yoon Cheong.’

Can Nokha, now in the body of Yoon Cheong, save the doomed girl group ‘Steel Blue’ and change the fate that awaits them?
