Welcome to the N.H.K. - Season 1 Episode 23 Welcome To Misaki!
Overview: Misaki’s mental state doesn’t seem like what it used to be, as she chooses an odd topic for their counseling session. It turns out that this is Tatsuhiro’s final session as Misaki is giving him a final exam before a graduation from the project. The graduation doesn’t go to well, because Tatsuhiro doesn’t think of himself as worthy enough to support Misaki, so he cuts all ties with her.
