“Love happens only once, but only difference is that the girl changes.”

“A girl only gets married once, after all. Only once for the first time, that is.”

“A real, true love that makes a human being believe in the power of destiny happens only once in a lifetime.”

“You know, there is only one letter's difference between lonely and lovely," I told him once when he was down. "There is only one letter's difference between loner and loser," he retorted.”

“We fell in love, despite our differences, and once we did, something rare and beautiful was created. For me, love like that has only happened once, and that's why every minute we spent together has been seared in my memory. I'll never forget a single moment of it.”

“But he had been in love once, that he knew. Once and only once, and a long time ago. And it had changed him forever. Perfect love did that to a person and this had been perfect.”
