I just realized something deal-breaking.... The MC is un-manga calm and collected when it comes to ero. I mean, under normal circumstances the guy would be dying of bloodloss, but not him. He is just here, observing the matériel.
Yup, Mobuyuki definitely got into the zone and let the "art" part of his brain temporarily suppress both the "social mores" and "horny teenager" parts. It says something about his budding professionalism.
P.S. Lemon-senpai is the hero(ine) we need, but probably not the one we deserve. ^_^
Lemon definitely star of this series, also mobuyuki calm demeanor, less obnoxious flustered facial expression different with over exaggeration stupid flustered reaction that you found in common harem ecchi manga make this more enjoyable.
Lemon playing the part of the perverted MC is actually hilarious because how "genre savvy" she is but she still falls for all the classic developments lol
