A shut-in girl discovers she can manufacture stardom with a keyboard and becomes obsessed with saving three girls nobody knows about. The show never condescends to its protagonist or treats her bedroom-bound obsession as something she needs to fix. Suko's blog doesn't just push idols up the charts, it rewrites what matters about them, and watching her fight another blogger over scraps of fandom energy is genuinely tense because both of them believe they're the only one who understands what their girls deserve.

Suko lives as a shut-in who adores idols and has an unusual gift: whatever idol she writes about on her blog becomes popular. When her sister forces her out on a trip to the supermarket, she catches a live show by Itrio, an idol trio based in Fukuoka. Suko resolves to do everything she can to carry them to stardom. Her plans run into trouble, though. Ryu-san, a charismatic otaku blogger, backs Mariko, an underground idol, and Suko has to compete with them. The result is a short-format drama built around music and idol fandom.
