WHILE the audience was enjoying his 'little performance', Astrid was already cringing inside. When asked to do something 'cute', this action was the first thing that came to his mind.
During his time as an actor in his past life, idols were everywhere. It's like there was a factory mass producing them. That's why, as someone from the same industry, it was inevitable for him not to see some of their performances.
After they performed on stage for some music show, the camera would always zoom in to some of the members of the group. Those who were chosen would then do poses that would make them look 'cute' or 'adorable' to the audience watching them. Which was also a part of their fan service.
Astrid did what was commonly known back then as a 'heart bite'. It was the first thing that came to his mind when thinking of something that was cute and easy to do. Of course, he also imitated the 'idol smiles' he saw then.
And what he did just now was the result.
