Angel Beats!, Kimi no Suizou wo Tabetai Recommendations
Both anime are focused on death, the unexpected, things left unsaid, and the jarring shifts in tone. How things can go from happy to sad at the drop of the hat, the brevity of things, how you don't end up getting to do everything you want to.
Ever contemplated about death? Well here's two tearjerking animes that would satisfy that thought. If you wonder what happens if you shoulder the weight of regret or guilt, and that it is left unresolved when you die, or the person that impacted those feelings on you is gone, then these are the perfect animes for you. Except Angel Beats is a series and it happens in the afterlife, while I Want to Eat Your Pancreas is before death. Both also has great songs ^_^ (btw take note that upon writing this review, I have NOT watched clannad lol). Both are in my top 10 favourite
