She's that excited over 2 million Yen? That better be monthly (or better yet weekly) cause that's only about 13.6k US.
If she is being paid that monthly it means that her yearly salary is closing in to being twice the salary of the best paid experienced veteran nurses in the world, while being just a fresh graduate that is still in training because she doesn't even knows the needs of her patients
So she got herself an extremely good deal, specially considering the average salary of a nurse being unfairly low given the amount of hours they need to clock in and how they are stuck in the middle between customer service, caretaking, and medical assistance
In fact the unfairness of nurse wages is one of the easiest fields to observer income inequality based on gender, since nursing is one of those fields populated mostly by women, which incentivizes them being paid badly
