I dont usually make reviews on the mangas I read, but this is quite literally the best oneshot I've read so far. It is the perfect blend. It ends rather peacefully to me. It may not be the best ending for the main characters but after all that, I can't help but be thankful it had ended that way.
It's melancholic but happy, its a great depiction of how someone copes with death of someone close to them. And how even if theyve done you wrong, you cant help but remember that person in a vivid and beautiful way.
I cant really put it to words but Goodbye Eri is so good, I'm grateful that I was able to obtain a physical copy to cherish.
