One Happy Family

(FrUK +FACE family fanfic. May contain swearing, smut at some points(you will be warned so don't worry) and lots of fluff and cuteness. Also abuse and kidnapping. Punk Arthur in this one as well. I don't own hetalia or the characters.)
Francis Bonnefoy is a hard working chef and co-owner of a five star restaurant he shares with his friends. Arthur Kirkland is a musician and, even if he does look like a complete punk people don't like to look at, a very well known Author. The two had known each other since kindergarten and has been married for a year now and both are completely happy with it. Though since Arthur doesn't really get out much unless Francis has allowed him to play at his restaurant, the Brit has been getting lonely in the house while Francis is at work. So he asked Francis the big question the adds two little angels into their lives, but what will happen once someone comes around to stop such a thing from happening?
