Sakura-san is a new employee so serious that she measures the decrease of her boss's beer with a ruler at drinking parties. Then there's Mizumi-kun, an ordinary salaryman who ends up mentoring this over-the-top, troublemaking junior. Although unexpected things sometimes happen, the two grow together in a flurry of activity. This is a human gag comedy that brings energy to those who are new graduates, those who were once new graduates, and those who are about to become new graduates.

The first episode is always available for free. A new free episode will be updated every Wednesday at noon.
