Im still wondering.. How do they kissed? I mean Human and Beast (⊙…⊙ )

They don't really kiss. Lots of hugging and forehead touches. I think there's kisses on cheeks, but that's about it.

And then there's licking and biting, of course. I think the author realized that you can't apply normal human-human types of physical interaction without it looking weird. It's all very sweet and lovely, IMHO.

Chew their face off... Nah, jk, just think of a puppy licking your face, or better yet BOTH!(●￣(ｴ)￣●)

Me either
