Hitozuma no Kuchibiru wa Kan Chuuhai no Aji ga Shite

Tsuyoshi, a 22-year-old third-year university student, spends his days juggling classes and a beverage delivery job, always accompanied by a strong can of canned chuuhai. Living alone in a small apartment, his mundane daily routine takes an unexpected turn when he becomes entangled with Yui Koriyama—a married woman he has admired since childhood. What begins as an innocent connection rapidly escalates into a boundary-crossing affair, blurring the lines between longing, desire, and morality.

Set against quiet nights and stolen secret encounters, this bold narrative explores the thrill and complications of an illicit romance—where every meeting feels intoxicatingly sweet yet fraught with danger.
