[SPOILER="Basic problem with the plot of the latest update.", but if you feel that in My Early Life the dev ahs made more in depth characters then consider this.
If you're just playing to see attractive young girls characters have sex then ignore this.
So the girl in Ch 19 being corrupted by the MC, but she was running around naked and having sex with in Ch 18, but now she needs corrupting?
Even if you make the argument that the MC is older and she's not into him at the beginning, then why isn't she hooking up with the hot young girl on the beach without being corrupted?
Going back to the standard formula plot does not work well with this character.
If corrupting her is the goal then the end goal should have been something beyond what she's been doing, which would have to be somewhat sexually extreme, i.e. doing softcore lesbian porn or turning her into an escort.
