They meet, fall in love , stay and then separated.
But they constantly stay in touch with each other.
After separation both of them feel the fear of loosing of each other, feel the worth, importance of each other and feel that evrythings was changed but not their feelings of love.....
Then till waiting for what ?????
Go and again feel the world jelous through ur togetherness.
Yes this is the constant love dear , which will not change at any cost or any situation. This is unconditional.
