If i've promised my sister a day out then I stay with my sister regardless of who rings or texts.
I agree with the above. A promise is a promise. If something suddenly stirred in Eric's pants after getting a message from Vi, that's no reason to break his word.
As I said before, it's unclear how the story will unfold, but there are a couple of potential directions I'd be interested to see.
The first option: Eric and Vi stay together and overcome all difficulties through mutual trust, love, etc. Before Part 6, I was almost sure they were heading down an NTS path, but now I'm filled with doubt... However, it's too early to say anything for certain. We're still at the beginning of the story, not even halfway through.
The second option: Eric and Vi eventually break up. There could be many reasons, but primarily due to a loss of trust. Perhaps Vi will start spending more and more time at the photo studio and less time with Eric. Because of this, Eric will become gloomy and depressed, tormented by his doubts. Seeing him in this state, Anya decides to find out what's wrong. Since she can't get any answers from Eric himself, she launches her own little investigation, with help from her sister, Maki. Together, they manage to dig up some dirt on Vi. Shocked by her discoveries, Anya tells Eric everything, possibly even showing him video or other evidence. Shocked and angry, he confronts Vi demanding answers. During their conversation, he remembers that he has some self-respect left and cuts ties with her for good.
In the end, Vi continues her photo sessions with Bruce. After all, she enjoys him bossing her around. Later, under Bruce's influence, she becomes a porn star.
And Anya doesn't miss this golden opportunity to claim Eric for herself.
If you ask which option I prefer, I would say neither the first nor the second. These are only some possible event paths that would be interesting to observe.
Personally, I prefer a third storyline direction, but I won't discuss it yet because I first need the game to answer a couple of my questions. I'm unlikely to get these answers in the next chapter, but perhaps in Chapter 8. We'll wait and see.
The only thing I can say is that this third option contains no NTR and has a happy ending for the main group of characters.
Finally, I have a request: let's pause the NTR vs NTS debates for at least a week. This is no longer amusing!
