Some kind of harem ending where they're all dating and MC end up in a giant open relationship with all of them would definitively be a dream ending for me I just don't think this is what Lestag has in mind. And trust me when I say this I am the first surprised I was definitively not expecting wanting to date multiple girl when I got into this game hoping for a good NTS story.
I think this is the biggest compliment I can give to him: what I did expect going in would not caring too much about any side character beyong the girlfriend but not only Laura has been what I'd describe as the absolutely perfect NTS girlfriend and really wholesome her friends have been an amazing surprise as well to the point I could see myself enjoy a whole game with them maybe just as much.
Ashley is done very well and instead of just being another stereotypical vn slut I think he gave her surprising depths with her being your patner in crime in "corrupting" Laura but still coming off as good and lighthearted fun and how most importantly she is really respectful of boundries regarding the kinks explored. It's also a surprise seeing an even bigger degen' than me concerning NTS but a welcomed one when she is really on board with everything that's happening and help you ease Laura into all of it.
Tara reluctance to admit her desires is also very charming and her personality bounce really well off the others. Making her lewd acts feels all the more rewarding because of it.
Now like I said I don't expect to have this ending but in the meantime could we do more lewd stuff with them I'd be more than happy to finally let Ashley experience her fantasy or have an occasion to fuel Tara's voyeuristic fetish.
