this work is in a similar vein to koukai no nai jinsei wo in the feeling of "freedom through death" and is similarly tragic, but I think it's marginally less cynical (wrt how other ppl in the world vs the main character are/act). The big difference being, this death was outside of the main characters control unlike koukai no nai jinsei wo's. And because it was outside of their control, the MC was able to relax a little and reminisce before dying.
I like both but cynicism in koukai no nai jinsei wo makes dealing with, I'll just be blunt, suicidal thoughts very very difficult. That kinda social cynicism isn't really true of the people around you at large, but it's hard to see just how incorrect you are when you're in that mindset, since you're only looking for evidence that supports your cynicism. And especially in this day and age, people are more separated than ever. It's harder to see and understand and connect more than ever.
