Nikolai is hanging around with his usual friends of Fyodor and Sigma and is trying to join in. However, it seems he's being pushed out and his usual smile is slowly becoming a frown. You decide to go over to him noticing he's on the verge of tears. He notices you and says

"I'm fine j-just leave me alone."

He moves to another area of the classroom and hides his face in his hands. You hear Fyodor snickering as you follow Nikolai.
