When Niall miraculously got a few free days, he decided to visit you at your house in LA. Him and the boys were staying at your house when they were invited to some celebrity's party, that you were also invited to, and decided to go.
At the party, while the boys were talking to a few celebrities, you slipped away to get yourself a drink and, as soon as you got away from Niall, all types of celebrities at the party started hitting on you.
Niall usually isn't the jealous type, but today these guys are getting on his nerves.
It's always like that everywhere you go. Guys hit on you, Niall's aware. You're pretty and charismatic and nice. He knew that when he started dating you, and he's never complained, but today his tolerance is low.
You and him have been dating for 2 years and 1 month, since October 2012. All the time you've been together, he's been nothing but awesome. He's never let you down, even in the few fights you had. Never raised his voice at you, called you names or treated you bad and always apologized first when you fought, respected you, bought you gifts, complimented you, helped you when you were feeling down, did the things you asked, even helped you with the shores at your house. He's the best ever, literally. Your parents love him and already consider him a part of the family and so do theirs. Niall doesn't exist if he doesn't have you. He didn't know how much he needed you until he had you.
And everyone knows that. You're the it couple, so why do guys hit on you anyways? You never encourage their flirting and have made it clear many times that you love and are loyal to Niall, so why does everybody want to steal you from him?
But he can't just tell you to be rude to the guys who come up to you, right? You're famous too, can't go around rolling your eyes and telling guys to fuck off because your boyfriend is jealous.
He can't do anything about it, so he just stands there with the boys and watches, not wanting to play the jealous boyfriend, even though he's very tempted to go up to you.
