[Gundam personally hadn't given it much thought, looking out so closely for her. They were all classmates, so of course he wanted to keep an eye out for them, and some subjects would need more seeing to than others obviously (changes were painful and violent, if they were alone for those who knows what could happen). The idea of putting these feelings out there so that someone knows this fact...well. She's mortal. Mortals need that kind of thing. That wouldn't be too hard...

The symbols though, that's something he can think about easier, address better than anything else.]

...it's a sort of personal rune. It's unclear why they would be that, but it's a possibility that that is the purpose of them. Runes similar to those that I cast every day in my spells, a symbol like that for Nanami...someone could be attempting to curse us. Even considering the methods of which they were left on our bodies is cause for concern. If they were harmless, then leaving them on our flesh would have been equally harmless. Painted, drawn, unnoticed.
