あらすじ

Rieta, staying with a military ducal family, decided to help Noel, the second male lead, by coaching him on winning the female lead’s heart. After years of guidance, Rieta was confident Noel would succeed. However, in a surprising twist, Noel complimented Rieta instead, misapplying her advice. Flustered, Rieta realized her friend had taken her words to heart, but not in the way she intended. --- Born with memories of the novel *How to Survive as an Ordinary Lady*, Princess Rietta Lise is next in line for the throne of the Kingdom of Lise. But after being sold to the empire by her father, a king who lives in luxury and pleasure, she enters the ducal Mayer estate. Upon realizing that Noel, the duke’s second son, is the sub-male lead of the novel, she’ll try to repay the duchy’s favor by making him the real male protagonist!
