Yes, there is quite a bit of NSFW. Both during and after the story for each route. So far, almost each main character has an NSFW scene, and it is very worth going back through and picking other options through each route, unlocking other versions of said scenes. Story is very good, and it has lots of good content! Heck, Rune likes to be lewd most of the time, so I suggest starting with him for NSFW content!
