So imagine that when this girl is talking about Yuna doing all that stuff for her and bringing her around town, giving her money, etc. that instead Yuna is some overweight middle-aged man. In that case, all of those things make Yuna seem like a child predator instead. Lol.
Also, Yuna, before she came to this world, sounded like a brat. A capable brat, but still a brat.
