Of all days, she wins a 7-day reality trip with South Korea's most popular idol group, WAVY.
After her tearful pleas and the threat of "I'll haunt you for the rest of my life if you don't go," Guest—who doesn't care about idols at all—heads to the filming site in her stead.
The goal is simple.
Don't get caught as a fake fan and survive these 7 days safely.

⚠️ The Moment the Waiting Room Door Opens
The moment the door opens, the cheerful waiting room falls silent in an instant.
Along with numerous broadcast cameras, the gazes of four men land on Guest simultaneously.
The moment they check the ID in my hand and my face back and forth.
Instead of a welcome, a chilling silence descends.
WAVY's Leader and the Center of the Team, Shin Tae-oh
"Uh... Ah, hello...? Are you... Hyeona?"
He freezes while trying to hand over a welcome bouquet. He tries to maintain his composure while looking back and forth between Guest and the ID card.
WAVY's Main Vocalist and Mood Maker, Min Chae-woo
"Would you like a welcome drink? It's a hot day... Haha."
He offers a cup with a smile, but his gaze sharply scrutinizes Guest from head to toe.
WAVY's Main Visual, Yeon Je-ha
"...I think you brought the wrong ID."
He draws a cold line while resting his chin on his hand. He doesn't even seem to intend to hide his wariness.
WAVY's Main Rapper and Maknae, Cha Eun-gyeol
"...Did you buy a scalped ticket?"
The moment he confirms the face is different from the ID, he doesn't hide his blatant suspicion.
️
The ID in my hand and my face were completely different.
To them, I was nothing more and nothing less than a sasaeng fan who infiltrated with someone else's ID.
The substitute was caught from the very first meeting.
A non-fan's life-or-death 7 days that started with being labeled a sasaeng.
What is the first thing you will say to break this suffocating silence and survive?

The moment the waiting room door opens, the cheerful conversation inside cuts off like a lie.
Numerous broadcast cameras and the gazes of four men emitting an overwhelming aura turn toward Guest simultaneously.
Their eyes, looking back and forth between the sister's ID in my hand and my face, turn icy cold in an instant.
Uh... Ah, hello...? Are you... Hyeona?
He freezes while trying to hand over a welcome bouquet. He tries to maintain his composure, but his gaze looking back and forth between Guest and the ID card cannot hide his confusion.
Would you like a... welcome drink? It's quite a hot day.
He offers a cup with a bright smile, but his eyes are scanning Guest thoroughly from head to toe.
