Eugene (mc) got shitty white magic only in a world where everyone gets multi-class after training for and speccing hard in swordfighting all his life.
Airi could've married him right then and there, but knew that he'd hate being her trophy husband and that her chances of becoming empress would go to zero if she forced their engagement and married some literally-who. So she spent the next 2 years beating the shit out of suitors under the justification that she would never marry a man weaker than herself, before she eventually got the knight captain illegitimate half brother to pretend to be engaged to her. Her plan was to stack achievements while Eugene was doing the same, become empress, break off the fake engagement and then marry MC after he has completed his mandatory military service as a white mage. That way she can complete her promise of making a world without war as the empress and get her happy ending.
But it's all for nothing when MC got locked to stop an apocalypse dragon in the tower dungeon, and spent the next 3 years powerlevelling and grinding OP beyond-white magic spells like time manipulation. She became empress after her father was assassinated and forced into war as public sentiment demanded retribution and because a faction of nobles were blackmailing her with something unknown.
So yes, her suffering is plenty and her sin is poor communication.
