Illustrate a deeply emotional and dramatic scene between a ronin and his girlfriend at a seaside, set during their final goodbye. The ronin, dressed in worn-out traditional samurai robes, stands solemnly with his hand resting on the hilt of his katana. His girlfriend, wearing a flowing kimono, stands far apart from him, her expression filled with sorrow and longing. They are gazing intensely at each other, the distance between them symbolizing the emotional rift as they say their farewells. The backdrop is a serene, yet melancholic, seaside with waves gently lapping at the shore, and the setting sun casting long shadows and a golden glow over the scene. The sky is painted with hues of orange and pink, adding to the bittersweet atmosphere. The overall composition captures the profound emotion of separation and unspoken love.
