Something interesting regarding Kavetham is that for a long time it wasn't a ship I was all too interested in thinking about, until I took the time to read Kaveh's written story
I had assumed that the falling out they had when they were younger would have been due to a pretty standard argument or something bad that happened, but it was something far more interesting, in my opinion at least
The reason for their initial friendship failing was that Alhaitham saw him too much. He saw through Kaveh in a way that made him uncomfortable, and he pointed out something that Kaveh himself was never able to face. It was not due to a misunderstanding, at least in the usual sense, but because of too much understanding...
It's just an interesting detail in their dynamic and it made me think about the ship more, and you know what? Yeah they are gay
