For anyone else confused about the number (217): OP had the numbers right when they were posted originally but the numbers have changed on Pixiv.

The Makeshift plush pre-order post (which was 202) doesn't seem to be on pixiv any more, so the entries after that (i.e. Institute, Petting, Task Manager, Shopping, Fine Dining, Sleeping With Cat, Borrowing Money, Fell For It, Literature, Cat Lick, Lingo, Hag Tutorial, Comprehension, Sweater, Worst Case Scenario, Commentary) all got shifted down by one entry; that's why this is 217 and Worst Case Scenario -- which was originally posted as 217 -- shows up as 216 on Pixiv now.
