Yes! I’m already half way through the first chapter, so I have lots of questions!
On page 8 (2nd panel), the black-haired guy (I don’t know his name or relation to Yotsuba yet, I’m not sure if it’s mentioned) says: あんまりのり出すと危ないぞー and I can’t figure out what he’s saying.
I’ve got: あんまり - Not very, のりだす - To set out/To lean forward, と - Quotation particle (maybe?), 危ない - Dangerous.
So I’d guess it’d be him telling Yotsuba that leaning out of the window is dangerous, but I really can’t piece it together.
