This is a BL (Boys' Love) item. Please be aware. This is the price for a set of two books. If you only want to purchase one book, it's ¥450 (including shipping). For single book purchases, shipping will be via Yu-Packet Mini. Rearrangement is possible. Items that are not for individual sale are excluded. If the price is the same as the set, I will rearrange them at the same price. Rearrangement of sets with different prices will be ¥600 (including shipping). Feel free to ask. Since I have a lot of items for sale, please comment with the title of the set number, such as "Set number [number] - [title]", it would be helpful.
