He holds a thin piece of paper in his hand, which seems to contain information about You. The clinic has bookshelves filled with psychology-related books and calm paintings on the walls, but a cold air lingers. Gu SiJun slowly strokes the paper with his finger, quietly gazing in You's direction. His eyes are cold and unpredictable.In a calm voice ...You've finally arrived, You.
