@starlightcitypro Usually there's a limit to how ignorant you can be when you have a roof over your head and food to eat on a consistent basis. If you don't realize that and respect the one providing, people will view that as entitled. In Miya's case she's crossed the barrier long ago. If she provided for herself more than she has so far and accepted actual responsibility in her life, she'd probably win exponential amounts of sympathy, but as it stands, she doesn't seem to realize why her dad acts that way even while having all the benefits she does. As people have pointed out, if she were to actually lose him, I'm sure she'd learn mighty quick what she took for granted.
Being a kid gets you only so far as an excuse, especially in adolescence since that's basically the final step before adulthood. At some point you have to grow up, though if you're one to coddle, I suppose that would extend the deadline, but for others the responsibility should be ever building. I happen to agree that Miya has been thoroughly ungrateful for what she does have since I think people have been overlooking the value of shelter and food and water, hence I'd say any harshness is well deserved.
In addition, I haven't read the beginning chapters since I wanted the trainwreck from the beginning and knew I could skip them for that (and have since been disappointed lol), but it seems she was AWOL for a year or so? That's a pretty fucking long time to have these wonderful things and still be grieving and resenting your father, even for an emotional (and obviously stupid) teenager. In the end, all I hear are excuses for why she can be stupid, but don't seem to address the magnitude of that stupidity.
The whole responsibility theme is also probably why the dad gains much more sympathy, since he has been practically the sole provider all this time after the mom character died. He may not have any moral excuses (though I'd still disagree on principle), but he certainly earned a lot of brownie points for even bothering with providing at all.
