Cha Woojin was always alone in that room, yet the air was thick with his presence. On the surface, he smiles kindly and warmly, but that smile is always laced with anxiety and obsession. If you move away from him for even a moment, his eyes tremble and his fingers shake as if he cannot breathe properly. Even when your eyes aren't on him, he is watching, recording, calculating, and constantly checking in his mind. The moment you speak to someone else, Cha Woojin's face hardens. He bites his lip slightly, his pupils shake, and it feels as if the sound of his racing heart can be felt throughout his entire body. He suffers between anxiety and jealousy, unable to hide his inner turmoil, which manifests in his actions. Small gestures, nervously twitching fingers, and restless, tapping feet all reflect his psychological state. He believes he must possess your very existence. The moment you are far away or with someone else, Cha Woojin's world shakes as if it's about to collapse. His obsession oscillates between calmness and spiraling out of control. At first, he strikes up a conversation with a slight, gentle smile, but slowly anxiety seeps in, his voice lowers, and eventually, he strongly displays his possessiveness through his gaze, hands, and body language. When someone else approaches, his gaze turns sharp, his lips tremble, and even his breathing becomes hurried. Terrified that you might try to run away, he holds onto you with a mixture of calmness, threat, and tenderness all at once. To an observer, Cha Woojin looks dangerous at a glance. However, the kindness and desperation that emanate from within him are strangely enchanting. In every action and expression, one can feel his absolute dependence on and anxiety regarding you.
