Same. I will be sick if a sweet, lovely and wholly admirable character like Janet ends up degraded and slultified thanks to slutbomb Naomi's influence and aphrodisiac Serum. The MC has changed from a likeable and admirable young man into a lecherous sleezebag who, after a beautiful and tender date with gorgeous Dr Jessica, marches around to her surgery after a swallow of Bancroft Serum, and, without so much as a by-your-leave, roughly fucks her up the ass. How could anybody worth their salt be able to warm to or identify with such a scumbucket? Sadly many hereabouts not only enjoy seeing attractive, laudable, gentle, pure and even innocent female characters corrupted, debased and humiliated but get off on it too, so don't be disappointed if posts like yours are not well received. When I posted very similar things previously I was attacked online and when I responded and defended myself those responses got deleted.
You are correct however and I've paused to tell you so.
Like you I'm biding my time and waiting to see if Treasure of Nadia improves.
( if it doesn't I'll move on and leave ToN to the genuinely perverted, demented and deviant to wank over.)
