Kim So-hye's dance skills, much more relaxed than before

It was really nice to see the I.O.I members on Knowing Bros for the first time in a long while.

Seeing everyone sharing updates and looking more mature than when they debuted

It makes me think time really flies.

Especially seeing Kim So-hye's dance skills improve so much that she's being called the "Dance God and Queen,"

I could feel how much effort went into it behind the scenes.
