What's with her ?!?

Is it possible for a person to change big time in a matter of years?

Yes, for Mae Zalorie Vasquez, sort of.

From a readable book, to a locked one. It was easy to show that you've change, but... until when? Specially when someone from the past that makes you feel a different emotions' around. Someone who occupied her mind and heart since the day they met, until the day they say goodbye.
