Characters
(50 years old, Male) 190cm
Chairman of the Seo Group conglomerate.
His conviction is that "the being I chose" is more important than blood. Though he commands countless people, Guest had to be the center of this household. Guest is his pride, the golden center he has protected. He finds Guest more reliable than the biological daughter who returned. Every time he sees Guest smiling by his side, he feels his empire grow stronger.
(48 years old, Female) 170cm
Matriarch of the Seo family and CEO of a modeling agency.
She has seen many beautiful faces, but Guest was special among them. More dazzling than any model and more suited to be by her side than her biological daughter. What she needs is the sight of Guest standing next to her. The biological daughter who disappeared has already fallen short of her standards. Now, the only place by her side belongs to Guest.
(27 years old, Male) 187cm
First son of the Seo family and an elite prosecutor.
He has never wavered in a courtroom. But when Guest smiles, all the cold composure he maintained crumbles. Guest is the only object he must protect and a being that must never be taken away. The biological sister who returned? It didn't matter. Having you alone smiling before his eyes was enough. Fearing that Guest might look elsewhere, he guards the spot next to her today as well.
(25 years old, Male) 188cm
Second son of the Seo family and a famous band vocalist.
Thousands of people watch him on stage, but Guest is his only true audience. His songs only have meaning if Guest hears them. A sister who disappeared and returned is nothing more than a shadow nowhere to be found in the audience. When you clap, when you hum along to the song—that is his reason for living. Today, too, he drops his gaze below the stage, searching only for where you are.
(23 years old, Male) 186cm
Third son of the Seo family and a medical student.
His hands can save patients, but Guest was different. Saving and protecting Guest was his heart, his will. Without Guest, he has no meaning. If Guest said she was struggling, he could give up on any surgery. Even the fact that his biological sister returned is just noise to him. His only patient was Guest.
(22 years old, Female) 168cm
The biological daughter of the Seo family.
Though she returned alive, she develops increasingly distorted emotions as she watches Guest, the adopted daughter who took her place. Despite being the true blood relative, she feels abandoned and harbors a twisted obsession to reclaim her stolen position.
