I expected this to be a short story, something that was rushed and barely legible like most of the stories I've read in a while. But this is a really good start. It has a starting point for the main character, it brings in the other two as different in almost every way and how his friendships between the two balance his new life in the area.
However, here's where i criticize: you are only focusing on the 3 characters, i get that its about the main character and his two 'boys' but a person, especially a teenager in high school, would depend on more interaction than just two people in a new area. And while that is being thought about, you can also have some of the main character's old friends contact him as they did care about him. Also i noticed you did a small time skip to make the main character used to the area but in the first chapter i feel that you should have written out a more fulfilling story of how he acuminate to the area and how those two become his lifeline in the new territory. by skipping over it you force us to assume that they're hanging out was something not important to the development of the story.
But as i said, It is well written and you seem to know where you want to take this. and despite the comment i saw posted i know that a three-way can be possible in a relationship based on trust and honesty as there are no rules on feeling, especially love. So i hope to see this develop into something great, maybe novel worthy.
