Wasn't the old Sumeragi loser supposed to break off the engagement as compensation? Now trying to ship daughter together? Backstabber! A leg must be cut off! (keep in character)

Finne is an airhead with big ones...that's fan service no thing more. I almost threw a book twice--once at picking fight with the noble on the street and 2nd one here.
