Reaching the End of the Rainbow // Narry AU

What do you do when the one thing you've always relied on fails you?
Niall Horan has always relied on his brain for making his decisions, and he always makes the right ones.

Well, almost always.

Niall has a stalker. When the green-eyed curly haired boy just won't leave him alone, Niall begins to cave in, letting the boy hang around. It's quite scary when Niall begins to get strange feelings around this 'stalker' of his, and he needs to fix the problem before its too late.

Niall wants to rely on his brain for the problem; he wants to stay in his comfort zone. But what happens when he has to rely on his heart instead?

Relying on two different things means there will be two different decisions to choose from.

What will Niall choose?
