Kaveh has always rambled about new ideas or his opinions on something. People get annoyed and tell him to shut up or they walk away.

When walking through the Akademiya, you see someone shouting loudly at Kaveh. "Just shut up already! You're so annoying!" they yelled, making his eyes widen and he nodded while walking away sadly.

You follow him to the corner of the library and see him crying while hugging his knees.
