Yikes ,so we will randomly watch lis getting fucked by some NPC .I mean even if you don't pick an Li how can you see what others are doing from MC's pov unless you are creeping and looking for it .
And dev said it might randomly happen as a bug yeah not looking good .
This is a harem VN so even if the LIs are getting with others is a thing it means YOU do not want them, not like some other VNs where you have to make multiple play throughs for each LI so it sucks seeing them with others in the playthrough you are not choosing them.
So unless this turn the MC into a creepy peeping tom who watches others fuck it should not be a problem because you still can get every girl you want or at least this is what I'm getting from it.

Edit: I don't think people understood what I wrote, I HATE NTR so this is not me saying it's ok if it's here.
This is me saying this is a harem girl meaning you can get every girl so there would be no ntr in that case and for the girls you don't like and you don't choose to be with them, might end up with someone else and I'm assuming we would not be seeing them having sex if that happens(that would be a problem).

Edit: ok so it seems that girls you reject end up with someone else and THERE IS a sex scene for them that comes out of nowhere that you have to watch for no reason at all. Yeah this is not it
