It’s friction. They can do whatever they want
Fiction*
Not all fiction are inconsistent such as this one :(
I think they meant touching directly. She touched the other two but on their clothes, not their skin so I think its okay.
In chapter 11 Violet extended his hand and the FL accepted it. They were not wearing gloves.
SHHHHH THAT WAS SUPPOSED TO BE A SECREEEET DONT TELL OTHERS
I thought a Princess candidate isn't allowed to touch men besides the crown prince. The female lead already touched 2 men since Renok told her in the train.
