You know, I always really appreciate it whenever an author understands that not every girl is going to bleed when losing her virginity.
Frankly, I find it to be a gross purity fetish that's based simultaneously in both an archaic fear of sexually experienced women and just general ignorance of female anatomy on the part of men.
So good on you, Savan-sensei! You get the 'Easy Google Search' award!
Another hot piece from Savan...Speaking of hot, Ayamiya's that but R-rah r-roh. If I was Tommy, I wouldn't get too serious with her. I mean, what adventures did she go thru to end up with that wonderful souvenir for him? And she's also little too free-spirited to do naughty stuff. And then there's that bold dude in sunglasses in the beginning, who's giving me bad vibes. He seems like the type that would eavesdrop on one of their "teaching/learning" moments and be like, "Ok, Ayamiya. You wanna be taught? Then it's my time to teach!"
For the moment, I'll trust that "black glasses" dude to be Ayamiya-ojou's chauffeur or bodyguard, and nothing more; note his and the maid's reaction to Ayamiya getting bopped on her head on page 2, for calling Toyama by a pet name ("Tommy").
