It was said that Kai often wanted to get hugged when sick during debut days.

It's more like a girl than Kai. But basing this off that Kai does have a feminine figure. Mmm~!
This is very hard for me. The person who he is holding is just shorter than him. So either pre debut.
Or someone totally different. I'd say its predebut for 'kyungsoo's' eyebrows are slightly thicker now.
Yet most likely not Kai. Yet it could be it's very vaugue right now.
