For another, all the pages are in color!
Otherwise, the story appears to be standard fare: young man at a company encounters and falls for the Darcy-like tough, fair, tall, stern head boss.
What makes the manga so delightful is that the young man, Ahn Yiyoung, is the de facto head of a group of misfit programmers. At least, one of the misfits is a programmer. The other misfits are a designer and a business planner.
They create an app in a garage and win a contract (after various misunderstandings). The company offers to set them up in a room, which turns out to be a dingy closet with non-working light bulbs. In one of the funniest scenes, the team considers removing itself to another garage until Ahn points out that if they move into a new space, they will have to return all the tech goodies they got with the money they would have spent on rent.
The boss of the company at first dismisses Ahn but grows to appreciate his role in the group. He was brought on as a salesman but is now the guy who keeps everyone on the right page and communicates their ideas to the outside world.
And this person is very important. As Joel Sposky points out in an article I like to read to my English 100 students:The difference between a tolerable programmer and a great programmer is not how many programming languages they know, and it's not whether they prefer Python or Java. It's whether they can communicate their ideas. By persuading other people, they get leverage. By writing clear comments and technical specs, they let other programmers understand their code, which means other programmers can use and work with their code instead of rewriting it. Absent this, their code is worthless.
The same could be said for the person who organizes the team and makes sure that they aren't simply playing with their new tech toys--they do have to earn money, so they can eat...and buy more tech toys!
In or Out understands this basic truth.
