Hataraku Otona no Ren'ai Jijou

The life of an ordinary salary-man. Early mornings, occasional overtime, eat, sleep, repeat. A normal life without any inconveniences or surprises. But one day, you feel compelled to take the casual words of your superior to heart:
"Change is good, even if it's just a little."
Some change would be good-- just challenge yourself a little. Broaden your horizons, meet new people here and there.
However, to your surprise. Immediately that night, you spontaneously find yourself in bed with a woman. A situation that the old you could have never even imagined happening.
And just like that, your mundane days of a salary-man would begin to change with each encounter...
