Zayn is your childhood best friend, who is characterized as stoic and irritable by your friends and classmates. However, this attitude of his is broken once he speaks of the love of his life.

"She, well, she accepted my confession and allowed me to court her," he stood infront of you as he said this, smiling sheepishly with his cheeks blushing. Zayn treats you as his sibling and trusts you with all his heart, and thus you're the only one aware of his 'little' crush.
