Hm, unhelpfully, this sounds similar to a few I've read but can't quite remember. The only one I can think of now (but it doesn't seem like BJ Alex...) is the second story in this one:

Thought I'd mention it on the off-chance it was the one.
I remember a yaoi manga I read that was a blur in my memory but I found it really interesting because I have an interest in writing too. It was about this popular author who has writer's block and then he finds a muse (and his work skyrockets lol). They fall in love too, it's kind of like BJ Alex lolol. But I know there's a manga like that! Everything's just a blur and I can't really remember. It'd mean so much to me anyone knows mangas like that T-T
