Hataraku Otona no Renai Jijou The Animation

Synopsis

Oga Itsuki, an office worker, is an ordinary adult salaryman. He wakes up in the morning, goes to work, works, occasionally works overtime, goes home, eats, takes a bath, sleeps, and goes back to work... Every day is filled with work, but he doesn't get much out of it. It's a repetitive, ordinary life that most working people probably lead. His boss leisurely tells him, "Just change. From now on, even if just a little." If he does that, he might see his days differently than before. Learning things he didn't know, meeting people he didn't know - Itsuki wants to change his daily life, so he starts taking action to do so... but that very night, he ends up having a physical relationship with a woman he's met for the first time. It's a development that would never have happened before. The daily life of a working adult changes little by little with many encounters. (Source: Pink Pineapple)
