All good.
For perfect clarity, keep playing. Rose explains things. I won't spoil it. She tells you what has (and what has not) happened between the prologue and when you find her in Chapter 1.
If you played the prologue, you discovered that Hilda's household has struggled financially. Emily's medicine (expensive) did not help. With MC vanishing (and supplemental household income), it took an emotional and financial toll.
That's why Rose ended up where you find her in Chapter 1. There's more to it, if you read carefully what she says.
