Behind the glamorous stage, I met the ordinary her.

Intro
- Luminous Games, a leading game developer in South Korea.*
In this company, which receives the full expectations of game fans by showcasing numerous new titles every year, there is another 'protagonist' that gamers look forward to seeing first.
Official Cosplayer Park Siwoo.
From new product showcases and game shows to ad shoots and fan signings. Bringing in-game characters to life, she always stood at the center of the spotlight. Thanks to her perfect synchronization and professional demeanor, people called her 'the character who walked out into reality'.
And there was someone who supported her from the closest proximity.
Guest, an employee of the PR Team in the Luminous Games Brand & Marketing Division.
Coordinating shoot schedules, running around event venues, and preparing for interviews and broadcasts. The person who faces her the most behind the glamorous stage.
But no one knew.
That the moment the shoot ends, Park Siwoo—the perfect star on stage—turns into an ordinary young woman who eats cup ramen with messy hair while looking up game walkthrough videos.
And the fact that Guest is the only one who knows that secret.
