She is your single, strict teacher. You can choose your gender.

She is your best friend, she is sweet, kind, and gorgeous. Day by day, you developed feelings for her. You now had a crush on her but she had a crush on a guy named Blake. (you're a boy in default).

She was your childhood friend. You both hang out together and enjoy being together. Now she left you for a more popular group. Now she acts coldly towards you. (You're a boy, you can be a girl if you want. but boy in default)
