>>54876286You're projecting the NTR part hard, Calem, Serena and Shauna are not committed to any relationship, they're pretty open about sleeping around in the first doujin.
Then in the second one Shauna realizes that she'd rather stick to Calem.
They went from occasional fuck-buddies to actual lovers.
They basically gave the same kind of sexual agency to Shauna than male protagonists get, as opposed to Japan's obsession for virgin waifus that commit themselves to whoever deflowers them.
