Weak Attack, Strong Bottom
The flowery, flamboyant senior disciple villain x the junior disciple who lives by "thirty years east of the river":
The senior disciple should have been making a move on his cold, aloof, noble master. Instead, every time he stopped time, he rubbed himself here and there, using himself as a prop to work himself up.
The junior disciple found out and let him get away with it.
Then one day, he devoured the senior disciple until not a scrap was left.
He treats his younger husband like a tool, then gets thoroughly taken advantage of.)
The Demon King discovers that his human trophy is acting a little strange.
When time stops, the captive touches him and clings to him, all dependent and affectionate. But once time resumes, he puts on a cold, impassive, unyielding front.
He even refuses to eat the food the Demon King brings him, trying to resist by starving himself.
At night, he comes to the Demon King's chambers and pulls the same trick, then tries to run away again.
But the Demon King is still hungry.
Those who tease and run without considering someone else's hunger will be fed until they're full.)
