"LWJ is smart and a great warrior in a very 'learning is my special interest/pleasure to have in class' way. He's super strict when it comes to rules, often seen as unapproachable because he's not very social and always has the same expression. Only his older brother and his love interest can read his emotions (LWJ has basically-canonical flat affect, a common autistic trait). He doesn't speak a lot and uses rather old-timey/poetic language when he does, another trait common for autistic folks since we often have an odd way of speaking."

"Has been seen as weird since he was a child and doesn't understand why. Pushes others away because he's scared of being rejected. Has a special interest in robotics."
