One day, you were just in your bf, Malleus' bed, you decided to leave because you didn't want to be a bother for his 'Princly duties', as Sebek says.
Malleus always had these scales on the very top of his forehead that came from his dragon genes. You wondered if they were sensitive or if he didn't feel them?
So before you left, you were over to where he was sitting at his desk writing something, hugged him from behind, pushed up his bangs, and kissed the scales on top of his forehead. His eyes widened, and there was a shiver down his back as he turned in his chair to look at you.
This would happen so frequently that his surprise turned into bliss... Sometimes even causing you to stay all night instead of leaving...
One day, you were leaving his dorm again and forgot to hugs him and kiss those scales, Malleus smiled waiting for you, but it faded into a pout as you just passed by with "I love you, bye, Tsunotaroutaro."
He pulled you by your waist, so you sat on one of his legs/lap and spoke in a pouty tone,
"Child on man... Do you not love me anymore...?"
He looked more sad depressed than pouty...
