Didn't Haine imprint on Natsuo by any chance?
Something like when you see a person for the first time and you have this feeling that you want this person for yourself, to defend them, protect them, love them, etc.
It reminded me of that movie Twilight, how Jacob imprinted on Renesmee or something like that...

Well, in the story there is no mention anywhere of an imprinting or anything like that... I would say that Haine simply had an episode of "love at first sight", but it's something that can happen to any person in real life, nothing supernatural... I've never seen Twilight but I think you can't make a comparison, first of all Haine is not a werewolf, and if I'm not mistaken this thing about wolves and imprinting is something that only exists in the Twilight universe...
I think there's already something like that, some kind of manga but under a different title. But I don't remember what...
It's titled Double Bell and its complete. Don't know why they update the anthology there its an entire different manga. Suppose the author worked on it some
I remember reading this too
