I never understood love triangles in films. I thought how greedy can they be to love more than one person. I thought why couldn't they just choose one. I understand now. How are you supposed to choose when u love them both deeply and the same? How are you supposed to choose knowing you would break one and they would never forgive. It is not extremely lucky or good to love two people who love you back. Its a curse.
