Think of it this way:
King's Adopted Child: *people, even royalty from neighbor countries, start plotting for her hand in marriage to get her ability*
King's Wife: *silence* *crickets chirp*
but is it legal there... i mean probably..? since it's the past. and it's not like he's in love w her or anything (i hope) he's just gonna protect her.. also that age gap.. can he not just adopt her?? like in that monster duchess story
