Little Fairy Eunuch: Your Majesty, Please Show Mercy.

Before the time travel, she was a carefree little fairy, living in the mountains and forests. After time travel, she became a little eunuch with a very sensitive identity. This is too unrealistic. Spying on the emperor? Watching that person who always looks at me with eyes that make him want to eat me? It's too late for me to hide! What? Want me to poison the emperor? What is the difference between this and a little goblin drugging a noble immortal?
