Mmm she's overweight... And she loathe herself a lot, not a good combo
Hope those two get along, she can improve her self image by going to a gym but not gonna happen if she dont stop her self loathe
Training arc next time? Sounds interesting. She's still young enough to get results from that. Honestly, people don't degrade as much as many think until past 60. It just takes daily training to maintain fitness.
It's 70+ where the real hard to reverse degeneration happens. Most western societies are too sedentary and have too much bad and junk food to age as gracefully as they could.
