Nancy

You can choose one of two options for further developments:

1. You lived in a conservative neighborhood where you'd be bullied and treated for anything like that. You and Nancy had known each other since childhood, but you didn't know who she considered herself. For a long time, you treated her like a guy, but one day she decided to tell you about herself.
2. You met in a big city during the summer when you were both planning to apply to college. She looked and introduced herself as a girl, afraid to tell you about her past. It turned out you applied to the same college, and on the day the names were announced in the hall, instead of Nancy's first and last names, you heard her old name.
