Why Love to Love?

Do you realize that most of films, songs and novels are about love, love and love. Why love to love?
I used to think that was a non-sense thing. Our life is not always about love, there must be something more than it, isn't it? If it is, then why are we so concerned about love? What is so special about love?

Even when i was falling in love, those questions still have no answer. But the answer seems to come when I lost that feeling. Maybe, its because being loved makes us somebody. Maybe, being loved means being needed by someone. Maybe, being loved tells us how it felt when somebody thinks you are special.
If those maybes are true, then our mom and dad have made us somebody! Yeah, they make us somebody since we were born. But, it still do nott answer why all those songs, films and novels mostly are about couple's love, boys and girls. I'll give you another speculation, maybe being loved by stranger teaches us how to respect his/her feelings and even try to respond positively. Whatever we did and do, mom and dad will always forgive us, but that stranger, that stranger whom you don't wanna lose, can leave you.
Another perspective that crossed my mind is, when we are falling for someone, we have some goals, like wanna spend more time with that somebody, or even try to keep him/her forever by your side so that you can grow old together. If life is about reaching goals, then love must be the most challenging one since the  person we wanna conquer is out of our control. All we can do is do our best, but we still can accept nothing in return except being hurt, memories, and some lessons. This is also explained why the phase broken heart is often harder for some people. Some people get down when they fail to reach their goal, the other have better immunity to compromise failure. The damages also depend on the gradient of love, the better we love, the bigger the damage.
So, now we know that we know that the consequence of loving someone is being hurt. Why still dare to love? At some point, I start to think that love is made only for the continuity of human race, making sex is not only about lust. Then the fact that we can love somebody without having sex ruins it.
As a human in this crowded world, we are craving for acceptances and acknowledgement of our existences, and being loved gives us those things, acceptance and acknowledgement. Why we are falling in love? I choose to answer that we want to be loved, so that we love. Then why we cant love random people? Because we don't need world's acknowledgement, just some people we care about, like, and adore.
Here I am stuck with that, thats all I can share for now. I promise to explore more, but maybe I have to wait for another adventure. So, please pray for my immunity to rejection and failure!

Sorry for my bad grammar, I'm trying my best. Anyway, thanks for reading! :)
