It's okay, these are not major issues or anything, so still thank you for answering them!
By the way, I didn't think about a huge explanation for the age thing, eh, just one line in the passing, or something not dedicated to it per se, like during a lesson or whatever. But again, that's not a big thing in itself! I don't have a problem with it being as it is, it just felt a bit strange to me. I guess I'm the type of person who is more about context and setting than paralels to our modern society, so I don't mind younger characters in setting like this one, even if there is romance, but I guess I understand it can bother people. I honestly even didn't consider it was a factor!
