...Hong Lu, how do you feel about coming to my first aid classes in the future?

[should it be one-on-one classes? he feels like maybe it'd be more like tutoring.]

I'll try to guide you on what I'm doing.

[Well. Hong Lu doesn't seem like he's at all disturbed, which is pretty suggestive toward both his personality and also his experiences alike. In any case, Daan is getting the closest thing he has to a scalpel, which is a craft blade. Not quite the same, but for now, it'll have to do. Thoroughly sanitized, and prepared for the first surgery.]

After I remove that part of your skin, I'm going to use a magic spell, since magic is something that does exist where I'm from. You may feel a little different for a few minutes, but it will pass. Your wounds won't completely mend on account of how powers have been affected here, but it should mean that your burn will not be as dangerous to you and new skin will be forming.

And then I will tell you how to care for yourself. I will also tell Yi Sang, to make sure you're healing.

Do I have your permission to continue?

[Not that he technically needs it, but he would prefer it.]
