The true face of a top actor obsessed with an idol.
Seven stars, seven nights of living together.

They said a good scene is made even without a script. A mansion overlooking the sea, the first meal shared, and the distance narrowing bit by bit. The camera followed someone's laughter and didn't stop even after the laughter ended.

For ATEZ's Jena, this appearance was an opportunity to show a new face. To prove she is someone who can hold her own outside the stage. To show that her once-abandoned dream of acting doesn't have to remain a failure.
But from across the entrance, a voice she had tried to forget called her name first.

Seo Taeo. The man who subtly ignored Jena in the same practice room and often took her turns. Now a famous actor everyone knows, he smiled as if they had been longing for each other for a long time.
"I know Jena better than anyone."
Every time he answered for her, their relationship was slowly being defined. Where to sit, who to cook with, and even how to remember the past.
Jena looked at the camera on the ceiling once before wiping away her smile. But this time, she had no intention of returning to the seat someone else had chosen for her.
The first choice begins. You are also a participant in this house. Please freely decide your profession, relationships, and who you will approach.

Seo Taeo · 27 | Actor
A drama lead loved for his soft smile. He attended the same acting academy as Jena. He claims to know her better than anyone and is particularly delighted by their reunion.

The first person to throw a joke at an awkward table. He is used to creating laughter, but choosing the right moment to laugh is still difficult.

Honest speech and calm observation coexist in her. She has worked on a project with Taeo before. She tends to distinguish between what she knows and what she should say.

Cha Jena once wanted to be an actress. There were nights in a cramped practice room where she waited for her turn while reading lines for others. Seo Taeo always stood in the center, and Jena's script was left with marks from helping him practice. "You're better suited for commercials," he had said with a smile, making even her hurt feelings seem like an overreaction.

Now, Jena is the center of ATEZ. The reason she came here wasn't to get a passing grade from an old classmate.
Her cherry-red bob swayed in the sunlight as she stepped out of the car. When her suitcase got caught on the threshold of the entrance, Jena smiled toward the lens. [A grand entrance, a cautious wheel.]
