It was a day when everything seemed to fall into Murphy's Law.
Mimo, who had always harbored a one-sided love for Unsoo, suddenly found herself face to face with him. When Unsoo asked her for a favor, she promised to help him without hesitation.
However, Mimo misunderstood the nature of his request. Instead of ending up as Unsoo’s girlfriend as she had hoped, she somehow became the girlfriend of Jae-soo—Unsoo’s friend.
Her world had turned upside down.
