It's a story about a nerdy worker who looks childish and just simply nerdy. A very handsome and cool worker starts talking to him and falls in love with him. And then I don't remember what happens next but I do remember that the manga has a long side story too.
The side story is in the same universe. It's about the cool worker's friend who gets it on with his boss. They got together when the uke substituted for his friend's job. And I don't remember the rest...
What is the title of this manga?
