Bochi recommended this to me because, although she said that she was tired at the time, this made her cry. I read this late at night and I had 0 patience whatsoever, so I skimmed through while absorbing everything and nothing at the same time. I did understand the ending though. This was pretty sad tbh. The last chapter hid different though (ch. 16.5) with the random guy talking to the old man who recommended selling one’s lifespan for money in the first place. Pretty interesting stuff.
