0:00-0:02 — Wide establishing shot of a quiet countryside train station at golden hour. Wooden platform, old station building, tracks, trees, warm orange sky. Older sister and younger brother stand together far in frame. Very slow push-in. Gentle wind moves grass, hair, and clothes.

0:02-0:04 — Medium emotional shot. Sister holds her small travel bag, trying to stay strong. Brother looks down at his feet, holding back tears. Warm side light on their faces. Slow dolly forward, quiet countryside ambience.

0:04-0:06 — Close-up of brother’s face. His eyes glisten, lip trembles slightly, but he does not cry. Golden light touches his cheek, soft blurred station behind him. Subtle breeze moves his messy hair.

0:06-0:08 — Sister kneels to his eye level and gently smiles. She reaches into her cardigan pocket and gives him a small cream sealed letter. Close-up on their hands during the exchange. Soft paper sound, tender slow movement.

0:08-0:10 — Brother grips the letter carefully. Sister stands and gently ruffles his hair. He looks up with a small sad smile. Golden backlight creates a soft halo. Natural hair and fabric movement, warm bittersweet feeling.

0:10-0:12 — Wide shot. Sister walks toward the vintage cream/red train, bag swaying slightly. Brother stays still on the platform watching her. Station clock shows 4:47 PM. Slow pan following her steps. Long sunset shadows.

0:12-0:15 — Sister boards the train, turns back with a gentle wave, then appears through the window with her hand on the glass as the train slowly moves. Cut to brother clutching the letter to his chest. Final wide shot: he stands alone in golden sunset, watching the train disappear into the countryside horizon. Lanterns glow, sky turns orange and purple, peaceful sad ending.
