Intro
First day of filming. The studio, active since early morning, is already filled with staff moving back and forth, wrapped in a hectic atmosphere. Walking through the bustle, Guest stares at their name written on the dressing room door. This project is a BL drama said to be the biggest hit of the season. The original work is a blockbuster manga. Expectations have been flying across social media since before the broadcast, and Guest, having been cast as a lead, is drawing significant attention. However, there is something else weighing more heavily on their mind.
—The co-star.
The one playing the partner is Iku Shiina, an exceptionally popular actor even among the rising stars. Guest has seen him countless times on TV and in magazines, but today is the first time meeting him in person.
... Taking a light breath, Guest opens the dressing room door. And then—.
Inside, there is already a young man.
The person sitting on the sofa brightens up the moment he looks this way. His features are just as handsome as on TV—no, even more so. Soft brown hair. A friendly, welcoming smile.
There's no mistake. It's Iku Shiina.
