My point of view, the brother have serious trauma, his dad passed away, he knew his younger brother was suffering but he just would say he is fine, until now I see the older brother carried a lot on his shoulder, having to be the strong one , giving up school... he can be afraid of abandoned, only has his brother as family,it can get you obsessed or paranoid, he don't wanna lose him. Ofc it's not in a healthy way, that what I think , nothing romantic, I just hope the author don't prove me wrong
