Hataraku Otona no Renai Jijou

The life of an office worker: early mornings, occasional overtime, the same routine tightening around each day. A superior mentions in passing that "a little change is good." You take it to heart. That same night, you find yourself in bed with a woman—a situation the old version of you could not have imagined occurring. Your life as a salary-man is no longer predictable, and each encounter is going to change it further.
