To me the ntr aspect feels a bit too disconnected from the actual story/chat. On one hand Liz will go off the rails after she cheated once and keep doing it practically every day, all while still acting completely normal in messages and being almost shocked by her boyfriend suggesting more revealing outfits. Especially with the (imho well paced) nts path it's a bit strange to see all the numbers in the ring app explode after a certain point.

But in my experience this is still easily the best game in that style by far, some details hit just right.

Small nitpick: when asking Liz to go to the office without a bra she'll casually mention she already did that, but she only did that for her manager which her bf isn't supposed to know yet. This could be an opportunity for a bit more back and forth starting with suspicion and optionally ending with some more nts encouragement.
