Yumeji has a big problem, and no, it's not that he's gay (for now, anyway). Despite his good looks, excellent grades, and talent for sports, he's not getting any, and it has everything to do with the fact that he's impotent thanks to a traumatizing event back in middle school. Nothing seems to help, and since Viagra is apparently not a viable solution in Japan, he's practically lost all hope—until he meets underclassmen Seiji, who's violent, tactless, and says whatever is on his mind. Conveniently enough, he's also in love with Yumeji.

Fluffy school story between a older and taller glamorous bishie uke senpai and his pushy pint sized seme love interest. You can probably already guess that the above pairing is not one of my favs. Despite all that I still pretty decent and I enjoyed the art.

But to be honest, Yumeji was so hot and adorable I spent most of my time reading it wishing a more traditional seme would come and claim his ... heart. lol

“Otona Keikenchi” has an attractive design in Seiji, but any goodwill created by that simply bleeds for the character interactions and general plot. It’s highly mediocre, and slightly annoying. The main pairing is effectively the butting of heads between a wimp and an autist. It starts and ends with one sided social domination. It lacks any nuance/“soft touch” which leaves every part of the story thirsty for character and dimension that extends outside of it simply being a vector for the sexual acts between the MCs. The final nail in the coffin is that the sexual scenarios don’t even end up being that engaging. This ...
