Need help finding bl manga title

Back again with another bl I cannot remember the title of. From what I remember the mc lives in a world of demons/hybrids? And he’s a human but hides that fact from others. The ml is a demon? And starts following him and is attracted to his scent? I remember horns being a big thing and the bigger they are the more powerful they are. Pretty sure mc has blond/light hair and ml has red hair from the illustrations I remember. Sorry if this is all over the place I’m also trying to find another manga where the ml is a dragon/ hybrid and I’m scared I’m mixing up details about the two If anyone can help I would really appreciate it!
