I only noticed this after uploading it, but I'm really not sure what's going on with their hands here.

Only Amber and Yanfei's left hands were shown here.

Eula's right arm is holding the popsicle.
Amber's right was on Eula's hip, where her left is turned 180 degrees trying to hug Eula.
Yanfei's left was around Eula's right arm, which looks kinda weird due to Eula's tanktop.
