Zayn Malik posted a heartwarming throwback photo of himself and Liam Payne asleep, with the caption "Love You Bro ❤️." In a lengthy remembrance caption, Malik wrote that he had found himself talking out loud to Payne.

"I can't help but think selfishly that there was [sic] so many more conversations for us to have in our lives," he wrote. "I never got to thank you for supporting me through some of the most difficult times in my life. When I was missing home as a 17 year old kid you would always be there with a positive outlook and reassuring smile and let me know that you were my friend and that was loved."

Malik referenced their dynamic, saying the two had "butted heads" from time to time. "I always secretly respected you for it," he wrote. He added that he was the "most qualified" musically in the group and that "we could always rely on you to know which way to steer the ship next."
