Grumpy Mikado is Anezaki's office slave until the upstart underling films something that probably doesn't have as much traction nowadays since regular porn can be found everywhere and anywhere, but Anezaki gets some fine shots of Mikado's double life as a nerdy otaku, so tit-for-tat, and there was that one drunken incident together ... This leads to doing regular guy fun stuff together and—gasp!—actual friendship until an asshole comes sniffing around and interrupts a horrific scene which seems to belong to a whole other manga. Umm, yeah. Except this is quite a good little story and the characters are realistic, so read it anyway. It won't disappoint you.
