Harry and Louis enjoyed their date that night. The next day Louis asked him to be his boyfriend and Harry said yes. 

That was the first time Harry ever kissed someone.

But that was a year ago. 

Harry didn't know that it was possible to love any one as much as - more than even- his tree, but well, Louis has proven him wrong. It has only been a year and Harry has never dated anyone else before, but he knows that Louis is the one. He knows that they will get married someday. He can feel in in his heart.
