I strongly believe that MC will lose the fight but his opponent now really wants to change the duel conditions and keep him for himself, likely making a fool of himself in the process. Aka, MC loses the battle but wins the war.
MC will then be "sent" to the weird southern noble whose place will be destroyed by the time he gets there.
