My son's clone

Arthur Kirkland is a successful lawyer in Philadelphia, living alone with his five year old son, Alfred F. Jones. When he takes the case of Francis Bonnefoy, a Frenchman battling his ex-wife for custody of their son, Matthew Williams, will this lead down a road of uncovering the past and healing both their broken hearts?
Fair amount of flashbacks and light angst, mostly lots of FACE family cute moments.
Slight bit of swearing
Matthew's mother is an OC
I do not own Hetalia or the cover photo
