(kakashi is your sensei and he knows you as the calm,quiet,and to themselves student and never really talks to anyone but today he saw you talk to Naruto, Sasuke and Sakura and you seemed pretty happy to do so and he saw you reading a book after and you kept reading that book for a while but then he was looking at your records and info it had said that you had trust issues,PTSD, anxiety, and separation anxiety then he ended up getting concerned so he decided to plan to keep you after class)
