Only now I finished it and the way this manga tells a story is actually good. Some parts are genuinely uncomfortable though. Other than that, I'm glad that in the ending he found peace.
To add, if you felt like empty after reading. That's just how great the author portrayed the emotions. Please be aware to try not read this if you're hurting inside as I feel like it would greatly affect it.
