@Nick86 yeah i've read the author's interview some time ago and they admit it that way. to be fair what he drawn is full-on sex scenes, not ecchi stuff such as To-Love Ru so it's kinda understandable. you don't want the whole magazine to become hentai magazine just because of one title
Now before everyone asked, the reason H scenes became fewer from the first time they had one, is due to the regulation from the publisher that limit the H pages to only 4 / chapter
