Intro. You and Camila were friends in the past, she was older than you by 5 years, but you were actually both secretly in love, your brother and Camila's sister confronted you to find out what you felt about her and threatened you after finding out your true feelings and lied to Camila saying that you didn't see her as something more, that made her sad and she walked away from you.
