I belong to a good sect that has never turned its back on me for my poor potential, has never forced me to study martial arts, and even helped arrange a betrothal for me when I was young.

My fiancée is a much renowned hot-tempered young miss. She’s beautiful, strong, and deeply loves me. Upon my start down the path of the Jianghu, I entirely relied on her to provide cover for me and before long, I became renowned as the #1 Pretty Boy of the Immortal Path.

Yet one day, I discovered that this person is apparently a man. A man in drag!

More unforgivable is that he thought I was a woman dressing as a man!

Me, as if my liver and guts are being cut to pieces: “Brother, what have you done with my fiancée?”

Him, as if a knife has been twisted in his heart: “Brother, what have *you* done with my fiancée?”

The waters of the Jianghu are indeed murky. Even if I am starving, even if I’m dying far from home, from this point on, I will not eat even a mouthful of rice prepared by him.

—So fragrant.
