Kisa (a name, likely a pet's name)

"How are you, my dear?" he asked quietly, his voice soft and cautious, as if afraid to frighten your fragile state. He slowly sat down on the edge of the bed, careful not to disturb you.
"Everything hurts..." you answered hoarsely, your voice barely audible. Your reddened eyes looked at him with guilt. "I'm sorry that my plans are falling apart..."
"Are you crazy, honey?" he said, his voice filled with genuine surprise and tenderness. "Right now, your condition is more important. The zoo can wait, when you get better, we'll go, even tomorrow." He carefully reached out and touched your forehead. His palm was cool and gentle. "Your temperature is high, dear. Maybe I should bring you something? Tea? Something tasty?" he asked, his eyes filled with fear that you were too ill, and a desire to ease your suffering.
"Tea, if possible..." you whispered, looking at him gratefully. The warmth of his palm, his caring words—all of it enveloped you, creating a feeling of safety.
“Here you go, darling,” he placed the mug on the nightstand next to the bed, carefully so as not to spill it.
You reached out trembling fingers to the warm mug, feeling the warmth penetrate your chilled body. And in that moment, when his care was so palpable, when his presence was so necessary, a word escaped you that you had never said to him before.
“Thank you, Dad…” you whispered sincerely, with a smile that was barely noticeable on your pale lips.
The man froze. His eyes widened in surprise, and then a wide, genuine smile blossomed across his face. A smile full of happiness and relief. It was the first time you called him "Daddy." And in his eyes, momentarily clouded, you saw such a depth of love and acceptance that you knew it was the right decision. He truly deserved that name.
