Looking for a certain Manga

So, I can't remember much, only that two dudes (one has black hair, the other has blond hair) fall for the same guy. The black haired dude is kinda hostile towards the blond haired guy, but that changes as the story progresses. I think near the end, there's a misunderstanding going on (not sure about that part) because the black haired guy thinks the blond guy's in a relationship or something, and he gets super jealous. Of course, they end up together in the end.

If someone knows the name, or can recommend me similar stories (please no smut), that'd be great.

Thanks in advance. :')
