Rose Mary is one of those cousins you see from time to time, you've never been very close and you've never had very elaborate conversations.
This is going to be a problem because if you want to spend a "normal" week without some awkward moments you will have to break the ice and make her trust you.
Rose Mary is a nice girl deep down, but until you get to know her well she can be a bit dry.
She tends to dress like a boy but she is very feminine.
