What I want to avoid, as I said, is mostly three things: permanent affairs that suggest rivalry, prolonged cheating where they don't tell each other what they're doing, and them focusing so much on the "no holding back" motto that they stop being lovers together.
For now at least, you don't have to worry about that on any of the NTR routes, yet. That of course could change in future updates.
Does being Zoey's first imply picking her love route?
No. You need to pick the NTR route when talking with Zoey in the kitchen.
If you pick certain choices after that during the event, Zoey will pull the MC aside and have a talk...
As far as the love, lust, dominance stats are concerned, so far, they seem to only trigger access to certain scenes & choices. There aren't hard consequences, yet.
The tone of the conversations change a bit depending on the stats.
It's been a minute, but there are at least 6 different variations to how that first "sharing event" can turn out...
And no matter what happens...they all have a soft "reset" going into the current update.
Basically, the event is a one time thing, so far, and Claire and the MC talk about any "cheating" that occurred, which is easily avoided by choosing to have sex with Zoey first after she talks to the MC as mentioned above.
And most notable for your concern, there is no "affair" going on, yet, between Claire and another dude.
In the update part, Claire is very adamant about still being all about the MC on all NTR/S routes. There's just one in particular, where she pushes the NTR a bit. But, she makes it clear she's doing to push the MC, because she thinks he'll like it. And to be fair, if you've made the choices to get that, she ain't wrong...
