Can't remember the title of BL

There was a college guy going out with a novelist or writer of some sort, but the writer doesn't show him much affection. Still, the college guy goes to live with him (?) whenever he's on break and tries to take care of him, like always buying him more cigarettes and telling him where he put them. This time, he left again and the writer started to miss him and sat outside his building, waiting for him to come back.
I think this was among 2-3 other stories. Any help would be appreciated, thanks!
