This is so good!!!
(I'm sorry I'm so late reading these! I wish I had come earlier!)

Part of the thing with the name is the style your going for. Lu sounds (to me) like a name of a fantasy type world. Names like the ones melissak suggested fit the world, and the ones I would say most fits your style are Keon or Yusuf, although the others are fine as well. The names sound a bit too rich for a poor boy, especially if he's an orphan. I looked up some names (although I feel like that's never very satisfying), and I found a few that were okay.
Ern
Pepin
William
Liam
Most of the others were kinda weird. Hope this helps!

I liked this one. More questions, of course, but that's one of the benefits of short stories. A good part. Keep writing! Oh, if you need a girl name, I always liked Jessie.

Honestly, I struggle with names all the time. I always search up: Random guy (or girl) names. That way it's easier. I only do it when I draw a blank on names though
