Sakura-san is a new employee so serious that she even measures the decrease in her boss's beer with a ruler at drinking parties. And then there's Mizumi-kun, an ordinary working adult who ends up mentoring this over-the-top, troublemaking junior. Although eccentric things happen sometimes, the two of them grow together in a flustered flurry. A human gag comedy that delivers energy to those who are new graduates, those who were once new graduates, and those who are about to become new graduates.
