Zero sense? As in just that last scene, right?

The rest of it made enough of it, except how "my magic will continue to work even when I'm dead" and "you're affected by my emotions the most".

I took the first quote to mean he'll stay immortal forever, while the second one's more difficult to interpret. The note mentioned "fate" - and adding up everything that's happened so far, seems to suggest that she thinks he'll have to clean up all her mess when weird things happen due to her fluctuating emotions.

Cute uniform + dead serious face was pretty cool. I could do with these cross-dressing transformations.
