Rio was living a perfectly normal high school life when cool and suave transfer student Tomo-chan entered his school. Rio admires his style, and watches as Tomo easily grabs the attention of the female student body – and of some teachers too. It's not until Tomo picks up Rio's dropped planner with a photo of his beloved idol, a male teacher, that they interact. Suspecting that Rio is gay, homophobic Tomo tells Rio he's going to 'cure' him by designing a special "Homo Fixing Training Regimen".
