A mysterious novel by Rio Enoki, "There's a Child I Don't Know in Room 209." - Title: There's a Child I Don't Know in Room 209 - Author: Rio Enoki - Publisher: KADOKAWA - Price: 1,500 yen There are no particular folds or noticeable yellowing. I purchased it last year and read it once, then stored it on a bookshelf. There is a scratch-like mark on the bottom, which I don't know how it got there. I apologize if there are any overlooked stains. I would like to sell it to someone who understands. Thank you for looking.
