I'd be interested in knowing what the king had prepared for ML, since he put in quite a bit of work for the other guys.
Then again, what could the king(dom) give ML?
Well, the only two thingsthat come to mind would be
1) Fix the eye he's lost
2) Make Sascha understand what she actually has done, and what she would need to do, to fix that (or at least try to fix it for real, rather than saying "sorry, but I did it for your sake ...", and "oops!"
I mean the king clearly keeps dossiers on all the important people, so of course he knows what's going on.
To me that's a bit strange, too, since having a clearly dysfunctional superhero in your country is a clear and present danger, and IF ML could be "fixed", there would be so many upsides to it, that putting in a bit of work would be worth A LOT.
Not to speak of how healing the hero's heart should be a nice thing to do, and thus worth it all by itself.
But hey - mangaka and the writers of light/web novels ... We may like the stuff they produce, but it ain't always the best.
