You don't know about love?

To somebody: stop complaining that you couldn't find true love in this world.
Just watch Titanic! If you still can't get any point on this matter, watch Titanic again...
Love is to keep a promise.
To protect the one you love will always come first.

No matter what happens, no matter how...promise me, never let go!
