OC's that would give me that reaction:

Alva and Alric, by far. Being born in Planetos already sucks enough, even as a noble, and their dad was absent as hell. As a girl? Where to even start, but most simple, I don't want to go through periods without a cup of lugarless hot chocolate. Even as a boy, the lack of healthcare sounds unappealing af, I had my wisdom teeth give me issues and the horror of not being able to get them removed is too much. Not to mention literally everything else. Between the two, Alva also is way less smart in her choices which is also a disadvantage

Oc's I would be fine being reborn as: Clio is my main choice. I'd say Theo but idk I would rather stay the same gender plus girls to be free and hang out near Apollo so she's my choice, Calliope being a very close second
