Louis broke up with his ex-husband and former band mate from One Direction, Harry Styles, and moved on to this new guy named Dylan 6 months after they broke up. Dylan is the type of guy who Louis was looking for. He was good looking, had a wonderful personality, had an amazing sense of humor and loves to be with him. Louis also has a kid from a fling he had with model Briana Jungwirth and Louis got full custody of his son, Freddie, and he gave the role of "the other father" to Harry when they were together, but after they broke up, Dylan has been the other father this entire time.
Harry styles is a single father to his 3 year old daughter Darcy but the week of Christmas Harry finds out that his parents are going to New York for Christmas so he's left alone but his friend and neighbour Louis who's also a single father invites him and his daughter to celebrate Christmas with his family
