NHK ni Youkoso!

Synopsis

Tatsuhiro and Kaoru are ecstatic as they review the completed version of the True World eroge they created together. Their enthusiasm is, however, premature as the game sales at the FuyuComi turn out to be quite poor. After packing his things, Kaoru leaves for his hometown the following morning, accompanied by Tatsuhiro who is to be seeing him off at the railway station. Feeling alone, Tatsuhiro falls prey to his delusions of grandeur. Misaki informs Tatsuhiro she'll be testing what he has learned since they began counselling by going out with him to Shibuya during New Year's Eve. Momentariously distracted by his paranoid thoughts, Tatsuhiro loses sight of Misaki and runs into Hitomi.
