I get your point, but i do feel like the manipulation here has kind of degraded in quality. Ironically, the ML seemed smarter before he went awol, back when it was more about emotionally manipulating the MC discreetly. That way he could at least feel loved by the MC.
Now, hes quite literally just physically forcing the MC into shape, and then aggravating him further with that recording of his mom. That part made no sense. If he had sweet talked the mom and made her feel grateful for being upgraded to a better hospital, that mightve actually made the MC stay with him. It wouldve guilted the MC into staying, but instead the ML guilted the mom which made the MC lash out.
It feels like the ML used to be more clever 'crazy possessive red flag'. Now he's just a regular 'crazy possessive' trope.
Yes! I think some people forget he’s the MC’s age too, not any older or smarter. Also, he’s tapering off of medication he’s been taking since childhood.
I recommend looking at the raws to kind of see how he behaves. He used to be more clever, I agree, but I think he just no longer cares to conceal his innate nature because he’s off his meds and also doesn’t care to understand others emotions.

i feel like people expect every story to be 100% wholesome when this is just not that. the other has another work that’s super cute, so i think who are hoping for something wholesome should just read that instead of criticizing this.
