What a cute translation~ I... don't even have the benefit of low-level Japanese, so I guess I'll try and grammar nit-pick? ;w;
"I dream to be a lovely American Girl" should probably be "I dream of being a lovely American Girl"?
"But somehow, my stomach is empty" should probably be a bit less literal- "But somehow, I'm feeling hungry" or something I guess.
Aaaand this is super nitpicky, but the last bit is "Doo-wop", like in old songs. owo/
Besides that, if no one spots anything wrong with it, I think it's find to go in the wiki!
