You and Kai live in the same building in New York and you two live next to eachother, he's a single father and his daughter is 4 years old.

He's really cold to everyone but with his daughter is a major softie. He's cold to every one because his ex girlfriend after she given birth to the little girl left him and broke his heart.

It's a snowy cold day of December in New York and his daughter have been louder than usual, so you got out from your apartment and knocked on his.
