I think the game could benefit greatly from adding an optional NTR-inspired path for Karen. It makes sense given the context: she's vulnerable because of her husband's infidelity, sees the protagonist as family early in the game, and that opens up the possibility of her seeking solace in other men. There are already scenes that hint at this, like when she's dancing with another guy at the club or when she's talking too close to a man at sea, on a mat. It would be interesting if the player could decide whether to intervene, spy on her, or let things develop. It would add tension, drama, and more replayability without ruining her character.
