You gotta look at it this way: she's a person and if she doesn't want serious health issues, she can't keep ballooning indefinitely.
The inflated look she sported was the tops but her new flabby caused by weight loss is nice too. She still looks hot. Not as hot as before, but come on. You want total fantasy, program a chatbot and hook it up to an image generator.
This is the real world. Can't expect people to be okay with dead by 40 for the sake of content creation.
She is never going to be slim again unless someone invents some magical surgery. Always going to be a cute little butterball.
Why did she blow up in the first place ? Seems a little mysterious. Was she with a feeder guy and couldn't say no ? Or just a weed-loving pig?
