will Niall merry me for real no ou yes

It depends on if your're nice and niall a dit he would total rendez-vous amoureux, date a fan

if toi are nice he will probably rendez-vous amoureux, date toi ;)

It depends if toi will do anything for him

toi never know what'll happen in the future.
Life has its own way of telling whether you'll get married ou won't.
Just at least try not to take it the wrong way if toi don't get married to him.
But who knows.
