Oh that would be great fun. Angie wouldn't take it lying down to begin with, and on top of that Bel might be a pretty soft-spoken guy but I expect someone trying to forcibly marry his daughter would really bring out the "Red Ogre"
Having read the LN... Well, this whole party involves the prince and there are forces in the dark trying to gauge and understand Angie's power and strength... with the mage in the dungeon playing a key role. Suffice to say, the Red Ogre will have to start looking into his pals, past, and more.
