After Failing to Cure the Villain, I Was Read by Him

I dressed as cannon fodder who was destined to be tortured to death by the villain, and the system asked me to heal him with love. I acted gentle and considerate for three years, but he was always gloomy and cold. Until the system suddenly announced that the mission had failed, I completely collapsed and complained crazily in my heart. The next second, he held my chin, and there was a storm in his eyes that I had never seen before: "Why didn't your 'system' read you lines other than poetry today?"
