A diary, or an essay, or rambling thoughts from an outsider drifting at the edge of the world.
I'm a shut-in.
I'm sensitive, timid, insecure, gloomy, and lost, but I also have "him."
Told in the first person, so there may be a lot of rambling from "me."
Based on reality, but the story is fictional. It might not even feel like a novel.
There are basically only two characters: "me" and "him."
Each chapter is a short piece, generally describing one little scene.
The overall tone is rather gloomy.
You may have to figure out some of the other things yourself.
Theme: Finding oneself
