While emphasizing her modest values and keeping Yuu waiting until marriage, she continues to play the perfect fiancée… However, after years in the business, the formidable Karen-chan inside Fumino begins to unconsciously show through. Yuu starts to suspect Fumino, and even his father hires a detective to investigate her background… What will happen next?
