I'm only in ch 2, but I'm not sure I like the premise of this. It's like he's being punished for finding a different aspiration in life since he no longer likes being an idol. It's like he's supposed to only live out his life for the fans and not have any agency of his own? I don't know...
At least he's acknowledging that everything he's saying are nothing but excuses. That's a start. And I hope he survives, because I think he needs to atone for what he's done to his sister. Obviously, not all of it is his fault (his parents and their society passed onto him their warped beliefs about non-powered people), but he certainly perpetuated a lot of it.
