Please help :(

So I was reading this one story on webtoons (naver) and i was discover/canvas story. I wanna reread it but i cant find it in my library and i cant remember the name of it. What I do remember is that it was a bl story about angels and demons. I believe the mc (who was half angel and demon and was prince) was supposed to marry a demon guy. But they fought all the time and it turns out the demon guy used to be the prince’s hero and he really liked him.


I cant remember a whole lot but as it come back to me I’ll put it in the comments. If you could help me find it id be so grateful
