[Should've expected that. Kohaku has a habit of thinking that everything in her world is completely normal...]

It's something angels can do in my world. A human being around one might get into a better mood. Singing is capable of relaxing, and making one happy. Or at least forgetting their problems for a bit. But I am sorry, I don't think I'm able to grant any wishes here.

I do know how you feel, I kind of went through the same thing. I may not be able to help with just one spell, but I can at least make the pain dull.
