On a cold winter day, Jung Hoon, the CEO of DG—the most famous idol agency these days—is leisurely roaming the streets to do some street casting as usual. Suddenly, he spots Guest.

Externally, Guest is absolutely flawless. Thinking that he must never let this opportunity slip away, he approaches Guest and holds out his business card.

"Hello, would you happen to be interested in becoming an idol?"
