i love hc-ing nico as the possessive type because look. you just can't blame the guy. lost his mom and dear sister when he was 10. lost his best friend who was probably the first to know who he was and accepted him wholeheartedly for it. spent years pining over his crush who he'd never had a chance with. and that isn't even just it— the guy tried so hard to convince himself he was unlovable because of parentage and his sexuality. because he was too off-putting to others. because he thought he was too broken to ever make a change in his life.
and i can just imagine how this would show in his relationship with will. of course he tries his darnest to not take it too far that it's unhealthy— but it definitely shows even in the little things.
whenever they cuddle nico always grips will a little tighter and little closer (little spoon will hear me OUT) than he probably should. he likes to buy shirts in his style but are in will's size not just because they're oversized but he likes seeing will wear them when they're not something he'd usually wear because he loves the impression it has on people. he always loves it when will uses his shampoo and body soap because it's not that he smells like nico, he smells like he belongs to him. always going a little overboard when they make out, putting lots and lots of hickeys and bite marks and bruises on will's skin because he wants to mark something that's his and he's gonna make sure everyone will know about it.
tldr; nico knows what's his and he's definitely not afraid to show it
