Dad, Where's mom?

Louis and Eleanor had one child, the energetic little Kevin and they all lived happily until they got the news that Eleanor had cancer and it was too late to treat her.

Kevin grew up(until 5) without a mom, and his biggest wish was to have that one missing family piece.
Louis went on date after date but never seemed to find the perfect mother for his son until the little guy went out and chose the perfect mother by himself.

Larry Stylinson if not obvious.
Will be bottom Harry in future, so you do not get false hopes <3
