Nagatoro already has the worst biweekly schedule, and on top of that author takes extra week to draw his fetishes and make you buy it along with main story. Thank god I don't have to pay for it. Looks like someone got too cocky and hasn't heard criticism from editor for a long time.
Canceling Deluxe edition was a big mistake, as Nanashi completely lost any sense of responsibility for bonus content and stopped add something for main story right after volume 12.
Want to go back to doujin and take a break from drawing Nagatoro? No problem, but don't make Nagatoro fans pay for your vacation
