I thought it was rather comical that Argay (name probably wrong, the billionaire) who has been openly hitting on and seducing a married woman leading up to the island....then gets morally offended that she's married and kissed him earlier. Even with Rick being there on the same island, the billionaire playboy who went through all the trouble seducing and leading up to the island gets a last minute moral adjustment, and Cora suddenly realizes she loves Rick so much that she could never betray him ever again.
It was jarring enough of a personality switch for Argay and Cora that it made me laugh. This update is for a vanilla playthrough where neither partner cheats. The dev screwed up combining the strait vanilla choices with the corrupt/cheating. The corrupt/cheating choices should have had Cora following through cucking Rick while he's in the next room. Just because Cora and Rick go to a guys private island together doesn't automatically erase all cheating and betrayals before.
I hope I'm wrong, but it left me with the feeling this Dev has caved to the anti-NTR trolls, and is adjusting his story on the fly to cater to their demands.
