Tatsuhiro Sato is woken up from his deluded dream of conspiracies, by his noisy neighbour playing loud anime music non-stop. All this could be put to an end if he'd just go next door to complain however Tatsuhiro is unable to do this because he is a “hikikomori”. He later meets a girl named Misaki, who will later change his life around.

After getting separated from Misaki, in the middle of Tokyo, Tatsuhiro runs into Hitomi ands ends up spending New Year’s Eve with her. They just end up separating after saying their farewells, when Tatsuhiro later meets up with a melancholic Misaki. The next day Misaki continues to spiral in despair as Tatsuhiro remains unaware, until their next counselling session.
