I liked it enough to finish it, but I only discovered this series a few days ago. I probably would not have been able to stand it if I had to wait months for the chapters.
It was obviously poorly paced. Almost everyone agrees on that. The author never really resolved why Shinohara, in the first time line, told Hinata to protect the painting. Yes, he may have realized the apple was blood and that Sora intended it to be a work of murder-suicide. So? That doesn't explain why he would tell Hinata to protect the painting when he just got attacked.
Anyways, it's... Okay as a story.

Separately, I do wish that the title were changed on this website. There is an English title that is fully official. There's no real reason to keep the title in Romaji other than for some weird fetishization in that kind of thing. Romaji isn't even used in Japan as a day-to-day writing system. Just translate it to "A Second Goodbye to You" as is the literal official English title.
