Sadly human Eden died before they were able to transfer his conscience so he's just an android that looks like Eden. I'm not sure about how he feels about mc but I'm pretty sure they're stronger than just master and android. We'll also see more of this being proven
And the reason he acts by himself i believe is because he was an android built purposefully to take on a human conscience and humans have more autonomy than androids, so my guess is that they built him as an android who can already think on his own but the emotions, such as crying, smiling, pleasure and things like that, are controlled based on the % of humanity their masters give them
I think the only thing they missed because human Eden died was his memories, reveries or soul, Eden's identity. I think it would be possible transfer his memories, personality and behaviors, if only he didn't die.
So he has emotions of human eden? Or he is just a normal Android? Cause he acts by himelf sometimes so idk, I’d like he has emotions for the mc and not just developed them because mc is his master but fell for him by himself
