Aji-3 and her jokes + robotic laughs *LOL*
I love how Chae Soo Bin acted her out. She did PD Jung Dae-Yoon advice to not act completely like a robot but rather add some ‘softness’ in her portrayal to make Aji-3 appealing more than being plain ‘robotic’ since she is a Humanoid Robot after all.

(I was just reminded of Sophia The Robot, a real life humanoid robot. She guested in Good Morning Britain and was also ask to deliver a joke lol*)
