In order to have the diaper changed, she must upload the condition of the diaper she’s worn all day on SNS after 5 in the afternoon.
Being naturally prone to polyuria, when evening comes the diaper is always almost at the max limit.
The vinyl tape around her waist is for binding (diaper will rip if forcibly taken off) and for support (to prevent the diaper heavy with pee from sliding down).
Her husband who works away from home has no idea that his wife is doing this sort of thing......
