The only person who treats him like a human being is the MC. Everyone else in this book either treats him as a well known celebrity, or a horrible scary person. Dude isn't heartless, he just doesn't trust anyone. The scientists treat him as a guinea pig, don't even bother trying to phrase their words nicely, and just act immediately hostile to him regardless if something goes wrong. They don't treat him like a person at all just because he is strong and can be a threat. They have never stopped to understand him and think that maybe he has a heart. Why would ML comply when you treat him almost like shit (forcing him etc) and ask him prying questions?? He is obviously not gonna answer and keep his guard up!
Not only does MC treat him normally (albeit a bit rocky at first cause duh, well known actor and rumoured scary person), he is also his guide. ML doesn't have a support system and he has been trying to sort his trauma all by himself. If you give a person who has been alone and hurt for so long, someone who stops to try and understand him, and take his side possibly, all while treating him like a normal person, do you think he is gonna let them go?? Do you think he ain't gonna even be somewhat emotionally attached to him?? The only thing that rubbed me off wrong was the smut scene, but him losing it makes a lot of sense cause he is an esper dude doesn't have a lot of self control when it comes to someone he actually likes.
Y'all need to be fr right now and think critically. If everyone is gonna be an asshole to ML, does ML not deserve to be an asshole??
