Kintaro Oe is a twenty-five year old student of, well, everything. After mastering every course at Tokyo University, he drops out to continue his journey of endless study. Driven by the sole desire to study everything he finds himself doing jobs ranging from being a cook, a swimming coach, a computer programmer, a cross-dressing pop idol, a rockstar, and even being a slave! The only thing that comes close to his love of studying is his love of women. More often than not, he finds himself in "sexually educational" situations, much to his delight!
Yui Sonezaki is in a bind. When her father left for Singapore years ago to perfect his curry technique, she was left in charge of Curry House Cooking Ganesha by herself. Now, with business dwindling, Yui will soon have to close down the shop - that is, until she suddenly comes across a starving man in the street! His name is Makito and he's a friend of her father, not to mention his curry skills are unprecedented. Together, the two decide to give Ganesha another try and make it the best curry shop around. However, many challenges stand in their way such as preventing the Suirei Corporation from taking them over, taking place in epic curry battles, training new staff and even competing with a local crepemobile!
While Kintaro travels around and Makito stays in one place, both mangas are about a very talented, yet perverted young guy who works in new environment. Both guys, thx to their extraordinary skills, save the woman who are in bind.
Also both mangas are quite perverted (though AtC is still nowhere near Golden Boy level)
I think the series are similar because in both series you have someone who want to do what he wants to do and while this person does what he wants to do he opens peoples eyes and they see what they want to do.
Golden Boy has more ecchi stuff and Denpa Kyoushi has otaku stuff and the art is 'better'
