Kami Eshi JK to OL Fujoshi
A fujoshi OL goes to a doujinshi event so she can meet the author that she admires. Meanwhile that same author was also waiting to meet the OL because of her twitter comments talking about how much she love the doujinshis the author made. But when the OL finds out that the author is a high school student and the author finds out that her fan isn't some girl of her age but an adult woman, some problems arise.
