从DLsite自购,但其中单图作者大部分已经免费发布于自己的Twitter中。图集是付费的,但及其便宜,建议有能力者自费支持。 Purchased from DLsite, but most of the individual images by the author have already been released for free on his/her Twitter. The collection is paid, but very cheap; It is advised that who have the means should consider self-funding it.
