So far I'm enjoying this, however a couple of notes. Moving from 1st person to 3rd person in a single work of fiction is taboo, to say the least. Jumping between character perspectives can be done, but never within the same chapter, and the chapter needs to establish very quickly that you're now looking through another character's eyes. Something else I noticed. When Introducing the female friend character in the first chapter, you made her appearance seem like the MC was unaware of who she was, that's the effect because this story is told with a first-person perspective. It is later revealed that she is his neighbour. You need to keep the fact that the MC is the narrator in mind. What the MC knows the audience knows, but at the same time, what the MC doesn't know, the audience isn't meant to know. That lets you do things in the background that can surprise both the MC and the readers at the same time. You utilise some of the benefits of first-person narration, but not all of them. And, your attempt to mitigate the drawbacks of the narrative style you chose, you create confusion for the reader. Anyway, I'll keep reading, because in spite of the flaws, it is enjoyable.
