How is she in a club for drawing manga, while having never shown anyone her work? It's not like she's new to the club, the first page says "she's always drawing diligently". Also, how are there only two people in this club?
Anyway, this is a cute idea, I could see this being spun into a series. Maybe different girls in the club could be different genres, and it could go in depth about their genre's tropes and the particular aspects to their layouts or visuals or something... or it could ignore that and just focus on the sexual/romantic tension with the girls (which is what would likely happen, and I'd still read it, lol).
