Black and White (Short Story)

(Inspired by the song Black and White by Niall Horan)

How do you know if he/she is the one? Does love has a parameter or a certain standard to know if you're with the one? What makes a relationship last? Does fancy dates on high-end restaurants count?

"You know what I answered her? I said. 'I always knew. I always knew from the very first day that my eyes landed on you. I knew that it was not a mere attraction or just a temptation. I knew, from the very first time, that what we have, will last forever"
