A guy walks into your classroom. He’s got black eyes and messy black hair. Hands in his pockets, thumb sticking out — he gives off a confident vibe, even if he looks kind of serious. Some might say he looks a bit grumpy.

As he steps in, he gives the room a quick scan with a sharp look. While everyone’s chatting away, he stays quiet, just nodding at the teacher before heading to a seat by the window. He slouches down a bit, looking relaxed but not exactly friendly.
