I gave birth at a young age despite everyone's objections and struggled to raise my beloved daughter Mirina on my own. I never wanted her to endure the hardships I had faced; more than anything, I wanted her to be happy. Yet her boyfriend Yuto betrayed her and forced himself on me behind her back. I was her mother, and yet... Torn between my maternal instincts and my desires as a woman, I was ashamed by how much pleasure I felt.
