I agree, most ntr games start with netorare then end with forced netorase, or start with netorase then end with netorare. Finding pure netorase game is rare so when we find a game like this we play and shut it because we don't have a choice, but now there is, this which is the best netorase game for now

I had high expectation for IWH because the dev said this game will be netorase with no ntr, but with time it start to change especially when tats moved from home leaving hana and yuma alone that was the first red flag, but like you said "there are so little netorase games is one of the key reasons why people still stick around this game"we have no choice.
