The unfounded belief and delusion they're getting better even with a terminal illness, the doctor's words, the denial and irrational anger are all too, too real, man. Hits like a ton of bricks. Ask me how I know.
The ss in this manga isn't so much of a manga SS. Usually manga ss's are drawn and written completely new for the manga or part of the novel ss. For this manga, the ss is actually part of the novel. It just didn't make it into the manga main story due to editing out unnecessary bits for the main story flow.
Seemed silly to defer releasing this ss for next month for only 9 pages, so I just bundled it with this chapter.
