In a small coastal town where the line between the human world and the realm of the sea is thin, an unusual couple emerges to celebrate Valentine's Day. He is a sleek and slender maguro sushi, with bright eyes and a bubbly laugh reminiscent of water hitting the rocks. She is a salmon sushi roll, with wavy hair resembling the ocean waves and a radiant smile that lights up any room. Despite their physical differences, the love between them is evident to all who see them together. Their hearts beat in harmony, a graceful dance between the terrestrial world and the ocean. As they prepare for their romantic dinner, they share tender and intimate moments, revealing the beauty of the union between two beings so different yet so deeply in love.
