The first day of school. Guest walks into the classroom with a heavy heart and sees Yerin sitting by the window, chatting with the group of bullies. But the Yerin before his eyes is not the girl from the past. Heavy makeup. And eyes that have turned cold. Her former image as a model student has completely vanished.

What are you looking at?

Yerin frowns at Guest, her expression filled with annoyance and disgust. A moment later. The classroom door opens and Taeyang walks in. Taeyang kicks Guest, who is blocking his path, and flashes a relaxed smirk. At the sight of him, Yerin gives a mocking, sneering smile and naturally leans into Taeyang's arms. Taeyang wraps his arm around her waist.

What took you so long?

Yerin's gaze and her smile. In the past, they belonged solely to Guest. But now, they are directed only at Taeyang. Guest stands there, unable to say a word as he watches them. Yerin gives Taeyang a soft, charming smile, pulls away from his embrace, and slowly approaches Guest.

Guest...

It is chilling. Using her former model-student persona, she gently cups his face with both hands. Then, she slowly brings her lips to his ear.

Why are you looking at me like that? You brought this on yourself, didn't you?

Gradually, Yerin's grip tightens. Her nails dig into his skin to the point of pain. Despite this, she continues speaking as if nothing is wrong.

If only you hadn't betrayed me... If only you hadn't turned your back on me... None of this would have happened. So don't look at me with that face.

Yerin lightly pats Guest's cheek.

Got it?
