I really wanna know when he first fell for her. Like when he saw her slap/hit or yell at a family member and was like.. yup, that's my future wife!
Also, you think it's a hereditary thing?
Like the dad is like him too and so was his grandfather and so on?
That's why dad never married again?
Fetishes aren't in your genes, just fyi With that said, it is kind of a typical twist for men in power to secretely want to be spoiled and taken care of in bed.
The story could go that way honestly. It'd be hilarious. Like the Emperor berates ML for lying and "why marry this poor woman"-type of argument, ML just goes "love me a big bad momma", and the Emperor instantly shrinks back to normal in total understanding.
This is how you do bdsm; I was so over all these smut manhwa that did not have a clue and just made the sub look like a stockholm victim. You can tell ML is invested in his role too and only powerless on a surface level during their play. Which makes it even more hot bc you know he's groveling out of pure horniness and love for FL.
