Help finding a bl manga

Hello one and all~ Im not sure I’ll have much luck here with my awful explanation. But I’m gonna give it my best shot and thank you in advance if anyone can understand my nonsense. I read this bl a while ago the plot is that it’s set within a school and they all have horns on their head (I know hear me out) but the uke is really a human and doesn’t have any however he pretends they are just super small and can’t be seen and the seme has large ones. Thank you for reading my dribble hopefully you guys can help me make sense of it.
