I don't know how to do a review but I'll try my best.
The death on green is a wonderful piece of art which has humor, interesting drama, compelling characters, good dialogue and an even better writing style, although I think you should revisit the story and fix a few mistakes you didn't notice while you were still writing.
My biggest reason for liking the story is the relationship between Eiji and Aranara. It feels so real and yet so unique. The way they met was pretty cool, and that reveal was truly well written.
"Bingo" and "I love my cat" have to be my favorite lines from Aranara. And Eiji is pretty relatable as a main character.
The fact that after ten years he still felt guilty for Lyse's death just makes him more nuanced and way more human than you'd expect. He's definitely far from being one dimensional, that for sure.
Anywho, I really enjoyed reading, thank you for creating this masterpiece, but that ending was unsatisfying, hehehe. So I hope they'll be a sequel, although that's probably unlikely.
I'm giving your story 5 out of 5 because of the way it handles death and suicide, and the incredible character development. Truly a wonderful read indeed.
