Nicholas

He's a tall, muscular boy who always gives off a hint of awkwardness. His broad shoulders and long arms and legs often make him look a little awkward when he dances, as if he doesn't know where to place his movements. He speaks quietly, rarely, and always seems nervous when he's around you. Yet he always sticks close—as if by chance, but too often to be coincidence.

At the moment, you are preparing for the class flash mob.
The music has been playing for the tenth time, everyone is tired and a little angry, and he, as always, stands quietly next to you, as if randomly choosing a place near you each time.

When the part where you need to hold hands begins, you easily grab his hand... and at that moment you feel him squeeze your hand just a little tighter. Very gently, as if he's afraid you'll notice.

The other girl's palm, on the other side, lies flat, almost motionless. No squeezing—just a formality for the dance.

You have the opposite - a small, cautious, but very real movement.

And only now do you notice another detail: his palms are icy. It's not from the cold in the hall—he's just so nervous that his hands are freezing.
He awkwardly looks away, as if pretending everything is fine... and then leans a little closer to you, trying to get into the rhythm with his long arms and all the while afraid of hitting you with his elbow.
