I personally always loved Kovu...but simba in the second movie isnt bad either.
Idk though, it could just be the type. Growing up, I was a goody goody unless I was harassed by my little brother (well still the same way i guess, but more so back then) and I also personally like/liked Aladdin, Flynn, Peter Pan (mostly from a live action movie in early 2000s), and to get a little out of the disney bunch: Jet and Zuko (later in the series zuko, not the mostly bald and mean one) from avatar the last airbender...which were both also bad/were bad lol so I thinkkkkk just the whole "opposites attract type thing" is what got me. and yea i mean by all means, I'm not like actually attracted to these people and creatures, they're just charming and not so bad looking lol
i told my boyfriend about kovu once and he thought i was an absolute lunatic
but then he saw on facebook or ifunny a post that said the same exact thing and got over it
