That’s a totally valid reaction. While writing the story I did wonder if Anna's attitude would have come off as unattractive to the player once THAT specific scene comes. Anna is a person I wrote be to somewhat immature and pampered. As the only daughter daughter of a wealthy family, she is someone who is often unable to take accountability for her actions and will just blame other people if something goes wrong.
A big part of the story is her maturing and slowly realizing how awful she was towards the player when they were kids. Along the way she will learn just how special the player is to her.
