Yeah, but you have to remember that this is his first real relationship, and he is a teenager, this automatically makes him dumb and immature naturally, same applies to Mary too, to be honest. He is desperate and confused, they have zero intersecting interests too. If Kendo did not interfere, they could have tried to compromise and fix their relationship in the future, or maybe, break up and learn from this experience and move on. But thanks to NTR aspect of betrayal, his zero self-confidence as an awkward nerd teen gone to negatives, so how can you expect him to grow a spine when situation actually breaks his non-existent spine? His already low self-image has got demolished by his lover and uncle. I am not saying that he doesn't have any faults or anything like that, as said, dumb teens do dumb things, especially inexperienced ones, but to expect him to grow a spine under such a circumstance is unrealistic. That's why like NTR in this game, yeah, it has some nonsensical NTR plot and magic sex god penis and all that. But at the heart of it, the relationship between Satoshi and Mary is a very well written and realistic description of most people's first relationship and love. It doesn't make MC and female lead mentally damaged to create an NTR situation, they had very common and realistic relationship problems as they are both going through their first long term partnership. And these issues could have been solved in the future, perhaps they would learn from this experience in future relationships. Introduction of the Kendo exacerbated their difficulties, and made it into a cheating situation, so hope of any resolution to those perfectly normal relationship concerns just gone out of the window. I don't put a lot of blame on him under these circumstances because he is not a grown adult man that has power over his young nephew. He uses that familial power to destroy his life and relationship under the cover of offering wise advices. So yes, I think a grown adult has more blame here than two dumb teenagers. But yeah, like if it's your kink, then it is fine to ask for more humiliating ending for MC, as ı said, ı have no problem with wanting to satisfy your kink and preferences.
