This is absolutely the right direction for development!!
That's exactly how it's described in online novels!
The naive heroine rubs aimlessly against the hero's body a few times in his embrace, and instantly notices something strange.
The usually dispassionate hero undergoes a transformation after just a few innocent rubs from the heroine.
The clueless (or foolish) heroine naturally doesn't understand what's happening, and not only asks about it but even reaches out to touch.
Then, the hero grabs the heroine's jaw and says, "Woman, you're playing with fire."
Before reading those books Chenxi bought for her, she truly didn't understand the differences between men and women.
She was genuinely innocent.
Not foolish.
Since childhood, she'd been a quick learner, familiarizing herself with human anatomy diagrams by the age of three, so naturally, she knew what the "strangeness" described in those online novels was referring to.
She was very familiar with the "pre-strange shape."
