Hi, I'll try to answer in the hope of explaining myself. Spoilers follow, again!
So, the problem isn't the themes covered, nor the story itself. In fact, I expected the truth to be revealed to us and Finn at some point. And that's fine. It was clear that Mert and Artyom had other goals and that their love for Finn was a means to achieve something else. Of course, I didn't expect it to go this far because, as I've already said, Mert and Artyom have no understanding of Finn as a person; they see him only as a tool, and that's inhuman, light years away not only from love, but even from any form of affection. And overall, I think that, against all odds, Mert and Artyom's behaviors and backgrounds have gone too far, so much so that it's impossible to go back while maintaining a credible and plausible narrative. The focus of my discussion isn't Finn. I understand his character, and it's also clear that he needs to grow, become the best version of himself (or the worst?). At the beginning of the story, he's a disheartened person, hiding in mediocrity, a victim of the traumatic events that have overwhelmed him. I can empathize with him (most of the time). So what's the problem? The point is what we know "outside the story." We can make a thousand assumptions and interpretations, but there's one thing we know, and one that Polar has repeatedly reiterated: Mert and Artyom are the main love interests (the secondary characters are secondary). So, if the author keeps repeating that we'll have a romantic relationship with them and to wait for the story to progress, given everything we know, I wonder: is this really possible? I can't imagine a solution that makes a HEALTHY love between them plausible. Of course, this could be a story about unhealthy relationships, that won't have a happy ending, or that aims to arouse feelings of unease, discomfort, and dark thoughts in readers.
But I repeat that Polar's premise is different, and I quote him directly: "The story isn't going to be as bitter as you might think." And even if I can't see a bright twist, I want to believe Polar's words, because I really need something good at this point in my life, even if it's fiction. In general, I think not everyone is capable of generating a debate, and that's always a good thing. It means this story has struck a chord (more than once, and painfully). I'm just afraid it's gone too far to redeem those who should be our love interests. Right now, I much prefer Berno, even Holger, even if he's a cannibal, at least I know his interest in Finn is genuine, because he's hungry 😂
