Sunao, a high school student, was on his way to school when he noticed a salaryman on the bus. A ring on his finger concealed teeth marks, raising questions about their origin. Could they be a sign of ownership? Or perhaps...
The very thought of the salaryman consumed Sunao's mind with fantasies until one day, he unexpectedly encountered him at his part-time job in an izakaya. Drunk and emboldened, the salaryman kissed Sunao...!?
However, these intense emotions were too premature to be considered genuine love. After all, what kind of connections could a high school student and a salaryman possibly have?
Additionally, the story includes an extra chapter titled "6th Year Obsession," which follows their relationship after the main events.
