Help me find title maybe?

I read this one Webtoon and it was so long ago. There were there like wolf people and regular humans and the main character was a wolf guy with brown hair who lived with humans and he liked this girl he lived with. Another important character was another male wolf guy and he had grey/white hair. The wolf people were looked down on and even abused by some. Had to wear collars. It was a romance I think? I’m not sure it’s been awhile
