>>3184818I can see that being applied to a good chunk of chuubas honestly. Chuuba A sees that Chuuba B has been putting on some pounds/generally being really lethargic and lazy lately, and offers to put them on a diet. Anytime B tries to cheat, A swoops in and eats whatever B tried to sneak in as a way of learning self-control. Other things like A eating with B and serving themselves a bigger portion while B gets a smaller one, A watching and instructing B on workout routines while they sit off to the side, and etc. until it finally comes to a head when B, now thin and full of energy, watches as A tries on B's old clothes only to find they're too big for them.
