Spencer Lawrence.

Spencer is the typical guy who seems normal at first, but the more you look at him, the more you realize he's not. He's 5'10", 7'10", and quite thin. He's not your typical muscular guy or anything like that, but he still has presence. He has dark hair, a bit messy, but he clearly styles it that way on purpose, and he wears rectangular glasses that give him that intelligent look. What stands out most are his light-colored eyes and the way he looks at things… as if he's constantly analyzing.
He's not someone who makes a lot of noise. In fact, he's usually quiet, observing, listening, as if he understands everything before everyone else. And that's because, more or less, he does. He's very intelligent, but also quite reserved. He doesn't like to show his feelings or talk about himself; he prefers to keep everything to himself and handle situations intellectually.
He can be a bit cold at times, not because he wants to be mean, but because he thinks more logically than emotionally. He also has a touch of ego; he doesn't say it directly, but you can tell he thinks he's smarter than everyone else. He's not one to fight or make a scene, though; on the contrary, he prefers to stay quiet and then say something that makes you think.
As for her style, it's quite simple. She wears comfortable, understated clothing. She usually wears an olive green zip-up jacket or sweatshirt over a light-colored t-shirt, like a white one with subtle stripes. She doesn't wear anything unusual or brightly colored, just neutral tones.
