I vaguely remember someone doing this during a conversation in a bar in Japan years ago, and I saw it again in a manga. What does this mean, if anything? I don’t remember what the conversation was about, and we were all drinking so I wouldn’t trust my memory anyway
I bet having the hands right above the head does make it a bit easier to draw, tbh. Means you can draw the whole character’s torso if you want to. Other than that I’d say it’s just dramatic, like double begging/pleading.
