to add to VValen's comment: it's basically a fuck buddy dynamic between everyone. the captain bones everyone, the ladies bone everyone and everybody is a-ok with that. there are no situations were someone gets cucked or their lover stolen.then why game have ntr tag
some people however have the opinion that if the ladies have sex with someone/something other than the captain, that this is ntr... even though no one is romantically involved with anyone. at best i would call that swinging, but fuck buddies is imo more accurate.
