These are my favorite boy characters. They're all buddies, from the left to the right: Corey, Alex, and Will. They met in high school and continue to stay in contact afterwards. This is what they would look like in their very early twenties.
I imagine Corey going to college for something in a scientific field. He's shy, but I would see his people skills overcoming his shyness. He is very curious, so he would probably go into a research team for pharmaceuticals or food research. Alex would have probably gotten an Associate's in business and start to work his way up. He would probably attempt to become a cop but not be able to handle the job, or pass exam. Will would work a smaller job, since he's rather content with being something like a working stiff: a manager at a local store or very small business. But they're still buddies and will hopefully always be buddies.
