help me thing this bl MANGA

They knew each other from when they were younger | don't remember if it was childhood or high school. Guy A shows up to guys B door and asks him to live together (he might've said he likes him in this part, I'm not sure) guy B accepts because guy B promises to support him.
When they get to his house it's super messy because he's very busy with work.
(Timeskip to a bit) Guy B realizes he has feelings for guy A. (Guy A has ALWAYS loved him) guy A at the same time realizes that he might've been too pushy with his feelings so he kinda backs off. I think they get into a fight
