Don't forget that the last two scenes Maryen spent without her eyepatch, so I still can believe that she just gets too greedy, since she still regrets hurting mc every time it happens. The one who wouldn't care would, well, not care, am I right?
The only thing that disturbs me is that, even looking at MCs agony from crushed lungs, which were crushed by her, not even a drop of tear came out of her eyes. It's inconsistent actually if we remember an opening scene, where mc can be accidentally killed which will make Maryen cry.
