SCYDE DYNAMIC!! this is my favorite dynamic for the two of them!
When Clyde falls in love, it hits him hard. He's so infatuated with Scott, and has no means to hide it. But Scott, who's a loser and has never had anyone love him, is completely oblivious to Clyde's feelings, even when he's showing them outright. Though he can't deny he finds Clyde a little cute even while they're friends.
I like to think Scott gets a little annoyed with how much Clyde starts to suddenly talk to him and hang out with him at school before he realizes that Clyde's actually in love. One of my friends gave me an idea that was a perfect example of this, which is below!
The thing on his arm is supposed to be a patch that diabetics use, Clyde's worried cause he's only ever seen Scott use needles and doesn't know if the patch is safe for him.
