Triangle Heart: Sazanami Joshiryou 1

Makihara Kousuke, filling in as a temporary janitor at the all-girls Sazanami dormitory, grows close to the residents—except for the distant Jinnai Mio, who refuses his food. Determined to win her over, he prepares a special dish once loved by the former janitor, igniting curiosity in Mio. Their guarded interactions soften into tentative trust, and soon, simmering tension flares into fiery passion as barriers melt away between bites and heated embraces.
