Hapinesu ni Yōkoso!
Welcome to Happiness!
Tatsuhiro meets up with an old high school friend, his class representative Megumi Kobayashi. When he divulges to her about being a hikikomori, she tells him she knows someone who can help cure his dilemma. She ends up whisking him off to an old dilapidated building where he finds himself listening to a sales pitch on a pseudo detergent product. Tatsuhiro manages to escape, but Megumi chases after him and tells him her depressing story. He buys the washing powder from her.
