A Un

Senkichi Mizuta, a pharmaceutical company employee, and Shuzo Kadokura, a war profiteer, are diametrically opposed in appearance and personality, but are best friends. Kadokura secretly loves Mizuta's wife, Tami, and both Mizuta and Tami are aware of it. The drama depicts the subtle relationship between the two men and the people around them against the backdrop of the times and customs of the early Showa period, in which both are aware of each other's love, but no one speaks of it.
