What does のそ mean in this picture?
A friend of mine said that it was "a moment later...", but I'm not really sure if that's the real meaning. What does this annotation mean?
「のそ」 is an onomatopoeic word describing a slow walk, slow body movements, etc.
We also use 「のそのそ」 and 「のそりのそり」.
You can forget "a moment later" for good.
