s it okay to make up your own surnames?

Yes it's perfectly fine cuz my friend did it 2 :) good luck

Sure, it's your story and your imagination. If it makes sense with the character and blends in with the story, atau just..something inside anda tells anda to use it, then go right on ahead :)


There's a saying I always have when it comes to writing;
"Trust the gut"
If there's any idea that suddenly strikes anda and anda from within that it's a good one, trust yourself. And go for it :)
Think about it if anda wish to, but I'd suggest that anda listen to yourself when anda have some type if intuition like this. ^^
