At the age of fifteen, the Emperor was essentially a scholar raised within the palace walls, delicate and frail. The Empress disliked this about him, so she subjected him to a series of "inhuman" transformations.
Under the "torture" of the Empress, the Emperor found himself attracted to her, despite her being disguised as a man at the time. During this period, he even thought he might be homosexual, leading to many humorous situations.
The Emperor placed a grilled mushroom into the Empress's bowl, "It smells good, should be edible."
Back on the frontier, they often ate grilled meat like this, which reminded them of those good old days.
The Empress picked up a mushroom with her chopsticks and fed it to the Emperor.
Accepting the Empress's feeding, the Emperor contentedly remarked, "Not bad, my cooking skills are quite decent."
