Ever Since I Was Tainted by a Eunuch

I was abandoned by the love of my life and used as a gift for the powerful eunuch in the palace. It was known that the chief of the Eastern Depot was cunning, abusive and violent, and everyone struggled to stay away from him. I thought that a secret guardsman like me would never have a chance to meet someone as important as him. Until His Royal Highness, who I had loved dearly for more than ten years, surrendered me to him in exchange for power.
