They say the keycaps in Kai's bag are his favorite items, like magic.

I was watching a video of Kai's favorite items in his bag, and an unexpected item appeared.

Kai is an INFJ, so he is afraid of giving presentations and stepping forward.
They say that the magical item that helps you whenever that happens is called a keycap.

With this one thing, you know you won't be afraid to perform or give a presentation in front of a hundred people.

I should get one too. I get so nervous every time I give a presentation.
