(you can find any series I post on mangago)
Mousou One Room by Lily Umiyuki
Plot - Mizuho, a guy who spent his days living off his girlfriend, has been dumped, leaving him penniless, homeless and to top it all off, jobless. He visits his childhood friend’s place to ask for help, and when there, meets his elder brother, Arikawa Sunao – the super popular porn manga artist! To Mizuho’s pleasant surprise, he offers to let him stay over for the time being. But Arikawa keeps sexually harassing him, saying that Mizuho is his material for work?! This manga's seme, is ofcourse, kind of a big pervert, but all in all, the story is quite cute and the art adds to the cute factor as well! But it's stil more of a smutty, cute manga.
Gouin Sakka To Makeinu No Hatsukoi by Nekono Mariko
Plot - Out of orders from his office, young model Nanami Jun becomes an assistant of a doujin artist! The said doujin artist turns out to be none other than the supermodel whom Jun had greatly admired from a while back, Kase Yuutai. Before long, he is immersed in joy, and even as he is messed around with and has to dress up erotically after references in doujinshi, he still wishes to love Kase! It is the love of an ore-sama ero doujin artist and an egoistic model. This is personally, one of my favourite manga series. It's pervy, cute, has a unique kind of plot with the model being a doujin-artist! It's a great short read for people looking for another unique series, that mixes 2 things that normally people wouldn't think go together!
