Unexpected, in the adult VN world, is being revenge-cheated by the wife if you're cheating. It almost never happens, and it's never unexpected because it happens only in boring NTR games where the husband is a total cuckold since the start. So a creative and original novelist could just put it in, as a consequence of your bad choices. I like surprises, I like cheating in games but I also don't like to know the result of my actions before playing. Like in non porn games, I like to be surprised and I like difficult scenarios, and this game seems to me it can accommodate this. Will it happen? No of course, because many (not all) people, very vocal, pretend predictable plots where the MC is the king of the universe with all the girls waiting for his blessed cock to give them the first real orgasm of their life. All the games, the same embarrassing childish scenario. How is this any entertaining, I really don't know.
