Cellphone KODE, where Yoon Doo-joon's deductive skills stood out

From the start, Yoon Doo-joon came in using the Messi nickname and calmly steered the conversation by throwing out questions.

It accurately identifies the points that fluster the other person and goes through them step by step, from MBTI to the home screen and playlist.

He was good at solving mysteries.

I could feel the experience from the mention of watching Infinite Challenge live or the scene where they used the YouTube Studio app to deduce the jobs.
In particular, the scene where they deliberately mentioned Seungkwan's name and watched his reaction while gathering Seventeen's clues felt almost like a deduction at the stage of certainty.

Even in blind talks, combining tone of voice and hints significantly narrows down the range.
