> By this going, i think Lysia and MC's one of the biggest enemy would be Lysia's parent Dad, for having playing the power struggles to raise their rank.
If Lysis'a definition of what she see was spot on, maybe, since MC's family is lower rank, Lysia's can cancel their engagement and put her to high ranking family for connection.
If she saw the trade of gold as payment of gold, then this was not far from happening.
Whats more, this is time of War, and if anything might happen, Lysia might be pulled out to MC's side, if ever her Family is in grave situation to whatever they take side on on the power struggle.
She might be use as a collateral payment, to pacify the upper ranking nobles due to some scheme victimized by them...
But then, MC will prove useful to gauge their capabilities, and his men will do the follow up actions...
