Otaku- is a Japanese term for people with obsessive interests, commonly the anime and manga. In modern Japanese slang, the term otaku is mostly equivalent to "geek" or "nerd". However it’s used to refer to a fan of anime/manga but can also refer to Japanese video games or Japanese culture in general. Thousands of manga studios in Japan are working to make them happy.

In Korea Doki Doki is the first manga studio. Main editor and director is Kim Myung Soo, 23 years old guy. He’s author of many mangas. For Korean otakus he’s a national hero.

But there are people like Lee Sung Yeol, who truly hate otakus and mangakas. Sungyeol hates them since his childhood. But his 25 years old best friend, Nam Woohyun is an otaku, also worker in Doki Doki. One fine day he asked him to start working at Doki Doki and Sungyeol accepted his offer.
