Zayn's different from everyone else he looks different from everyone he's shy quiet and unique. Ever sense he was little he got bullied for looking different from all the other kids becos he was mixed with all kinds of races but to a certain some one that made Zayn even more special. when Zayn got older he looked more different he also dressed how he wanted to and did what he wanted even if it's not "cool" he doesn't like to follow the crowd and the newest trends and such. He just likes what ever he likes and if he likes it and no one else does Zayn just doesn't care becos it's not them who's wearing it or playing it. Zayn is his own person he likes do draw and read comic book's about super hero's it may sound nerdy but that's just how he is he is a nerd he may not quite look like one but who cares cos Zayn doesn't. That's just another reason why he likes Zayn. Zayn is unique just like his looks as he got older he look's stunning with his perfect bone structure his gorgeous big hazel / brown eyes surrounded by thick lushes lashes, and he wants to laugh at all those kids that ever bullied Zayn becos he bet's they don't look even half as good as he does; It's all just kind of ironic in a way.
But sometimes Zayn does care he tries to act like he doesn't but he does. He locks himself in his room tired of reading hate towards him and sometimes Zayn doesn't like that he's different he wishes he can be normal like everyone wish he was as popular as the other lads like Harry, But he's not and that kills him.
And when Zayn does lock himself in his room trying his best not to cry but ends up crying anyway there's one person that comes in and reassures him;
Niall.
He goes into Zayn's room and tells him like he always does "Zayn you don't want to be normal you know why?" Zayn shakes his head wiping away the tears "Becos your exotic your like an exotic flower that everyone loves and wishes to be and if they do send you hate or of the sort they are just jealous cos your my exotic flower"
Then Zayn will stop crying and let Niall's words sink in he hears Niall call him that all the time but its like every time he hears him say it its like the first time and then he likes being different he likes being Niall's one and only flower correction exotic flower.
As for Niall he's always loved Zayn in fact he thinks that all of Zayn's qualities makes him like him more becos he is different he's not your average guy and that is something special.
