Male supporting role: After I left, the heroine regretted too much

Exhausting your lifespan to help you become the queen of a generation of singers, but you always lead me indifferently?
Treat you as the person you love the most, but you want to take my heart and become a fairy?
You have worked so hard to become your master and teach you, but you want to cut me into pieces?
To be your sharpest knife and help you become a generation of empress, but you are a running dog cooking a good bow?
You clearly promised me to grow old together, but in the end you just treated me as a substitute, and the original owner returned, but you kicked me away?
...
