Basically I’m looking for your typical male lead that seems cold but eventually becomes possessive towards the female lead (you’re mine, i won’t let you leave me etc.) but with the genders swapped.
Bonus points if the male lead is somewhat sweet and “passive” (in the sense that he likes it, even if it’s after some time/knowing the female lead better).
I’m ok with it being soft or very problematic. Things like making it impossible for the ML to leave her world, initiating the physical contact and basically being there for him no matter what add points, but it doesn’t have to be that extreme.
