Question!

I'm also kinda confused with the whole situation like the lycan and vamp part I don't understand can someone explain please

This from my perspective so it could be iffy. Basically marking is putting a certain scent that only you and the other person find calming and alluring, other lycans can still smell it but it would be of disgust. Take seolhyun and hwa fro ecample, they marked when they were Young trying to escape and it was at that point where seolhyun can't find other lycans scent alluring/calming he only found hwa's scent to do that. From a vampire perspective I would say since they don't have the smell of a lycan they can't tell who marked then, but and this is a big BUT I feel like they can't have sex with someone else cause it doesn't feel right unless its with the person who marked them. Again this all from my perspective

I see~ that kinda makes sense. So do they just rub them once with their scent and it will linger forever as if they got marked?

Again my perspective, but I think they're has to be a high amount of certain emotions that makes the marking stay again seolhyun and hwa they marked each other when they were falling(I think) so the adrenaline emotion of protection and reassurance and wanting the other person was fine helped them mark each other and allowed the mark the stay. But again my perspective and how I interpreted it and picked it up, different view from everyone

Ohhhhh hmmm so uhhh how do I sya this.... Uhhhhh...... Like what happens after they mark their partner? Do they feel some sort of idk stronger feeling toward that person or is that only the main reason you can mark someone or can they also mark strangers?? Was that mentioned? Thank for explaining that part tho

Same as omegaverse i guess, basically they only will feel attracted towards each other scent. I was hoping the 'marking' method is more obvious like to bite or transfer one's blood into the other's mouth but yeah

From my pov again. To me yeah the feeling for that person is stronger. I don't think they mentioned it, it's just what I picked up while reading

Oh OK thank you I'm really slow on these stuff sorry thank you again for sharing with me your thoughts(づ￣ ³￣)づ
