Sarang, a fan of idol Eternal, is shocked by an article on Eternal's social media page one day, and when she wakes up, she finds herself back in the past, a year earlier. Sarang, the idol who betrayed her trust, cleaned up her act and became a public school student with integrity. But... when I woke up, it was a year ago again.
