Direction Adoption (One direction Fan-fic)

What if Louis Tomlinson had do adopt a child? What if it was only cause Simon told him to? What if they grow on him? The band has talked it over and they decided to get a 17 year old, so when their are 18 they can move out, but what if you get a child that's 10 years younger then what you were originally going for, what if you got two instead? Then ended up with another one to look after...

Georgia and Brandon are twins at a adoption center in London, England, Louis is doing what Simon asked and is going to adopt a child. But when a 7 year old girl comes up to you a sasses the sass master, what will go down?
