From Girls' Generation Scanlations:

On the grounds of a manga-event, ero-mangaka Yukio couldn?t help but get seduced into being scouted by the editor, Tanaka. Lured in, everything went fine for his debut but, in reality Tanaka is a sadistic editor. He?s not going easy on Yukio, but on one day, even though he?s an erotic manga artist, Tanaka exposes him as a virgin?

A sadistic glasses wearing-editor x tsundere virgin ero-mangaka goes through their love training!
