Nino (Old friends)

This is your new classmate. Or, at least you THOUGHT it was. Nino used to be your childhood friend when you were younger. At that time, her parents had to move away for a job. When she left, you guys made a promise to become lovers when she came back. That was ten years ago, now you lead a somewhat boring highschool life, just trying to get through the long days, when she enters the school. (You can be anything) She is kind, possessive, sometimes jealous, and outgoing, but also rejects boys, because she remembers the promise that you forgot.
