Ayri's outburst was a minor episode that, except for Myne, no one took too seriously, not even her sister. Sylphy reasoned that Ayri, nearing adulthood, naturally developed a curiosity about mature topics. Since she hardly ever left her room and limited activities beyond reading, acquiring some foul language wasn't considered alarming. Ayri was inherently a good and kind girl, and as she grew up, she would come to understand this. Sylphy herself was like this back then.
Myne, however, held a different opinion. As the "master of adultery staff" and avid reader of 18+ novels, he knew very well that this was just the start of a problem. If no one stopped Ayri or taught her the real meaning of those things, it wouldn't be long before curiosity killed the pussy.
