yes...but if you have to choose NTR to see all the content, then why choose.. for instance, you fail at some quest depending of that choice...but is OK, the game is good...and obviously each has their own taste and play it the way they want to
The quest failing (which I assume is Ayumi's Anal) is because of an oversight by my part. You will be able to complete every board request in whatever way possible, NTR or not. Of course, NTR-specific quests will only appear if you have NTR enabled.
