A young girl named Kim Nana, around 10 years old, stands outside a humble traditional house surrounded by cherry blossom trees. She wears a light pink hanbok, her eyes full of innocence and curiosity. Inside the house, her father, Commander Kim Dong-in, a strong but kind man in royal army armor, receives a scroll from the king's messenger. The atmosphere is tense yet peaceful. Nana runs up to her father, smiling brightly, holding a small flower. Her father kneels and smiles at her gently, brushing her hair. Suddenly, a royal horn echoes in the distance - signaling his immediate departure to the palace. Nana's smile fades as her father stands, places his sword at his side, and walks away slowly. The wind blows softly, petals fall around her as she watches him leave, unaware it's the last time she'll ever see him.
