For Gus, I like that he is able to distance himself from his past and his urges. I see him as a natural intellectual. Goos job on the consistency.
For Tyler, I'd like to know more about him. Im sure he is more than a dumb vain shallow jock.
The interaction of the 2: so far expected from 2 complete strangers getting to know each other. The sexual tension from Gus has yet to be shown to Tyler. We know Gus is attracted. But Tyler does not. We already know Tyler's sexual need for Gus. Making the connection between the two without Gus surrendering to lust or Tyler becoming bullied would be nice. Personally, I like both to grow into muscle beasts.
Keep going. No pressure. Take your story where you want to take it. Will be waiting for the next part.
