This is the only thing that comes to mind when I think about writer seme/train/uke unable to read, but he does learn how to in this one.
Perhaps there are more details your remember ?
I love this story...especially the second one :)

All i can remember is that the seme and uke get on the train together in the end. The seme is a writer. In the end you find out the uke did not know how to read. the uke's roomate was Bun i think. i could be wrong. please help me find it
