One of the things beyond human control, is who we fall in love with. Love has its own "God". It has no limit on religion, race, sexual orientation, social or economic class, or anything else.
Filo and Sofi are a couple unable to express their love for each other due to their different religions. Even so, they believe that religion should be used to unite mankind, not divide them. Therefore they continue to learn and understand each other unconditionally. To them, no religion is wrong. They're all just different. It's narrow-mindedness that is our mistake.
