It's really more of an extension of their emotions than anything. That is to say, the attraction is more emotional than physical. Uchihas are full of feelings but are kind of too fucked up to find a healthy outlet for them, even when they're honestly trying to have a functional relationship. And it is functional. It's just also unhealthy. But basically he finds it comforting and pleasant because he likes feeling close to Sasuke.

He's aware that it's not normal, but idk, I have hard time imagining advanced bloodlines NOT keeping it in the family a lot of the time, so it doesn't bother him as much as it could otherwise, particularly from a moral standpoint. Though he does worry about being good for Sasuke because he tends to doubt that he is.

Are there any memories that you're particularly looking forward to Sakura getting back now that she's been in Aather a bit longer?
