In a secluded coastal town, where the boundary between the human world and the sea is blurred by mutations, an extraordinary couple emerges to celebrate Valentine's Day. He is a sleek maguro sushi, his eyes glowing with an otherworldly red hue, and a laugh that echoes like sonar through the depths. She is a salmon sushi roll, her hair flowing with iridescent scales, and a smile that sparkles like bioluminescent plankton. Despite their mutant forms, their love transcends the ordinary. Their hearts beat in a synchronized rhythm, a fusion of genetic anomalies and shared affection. As they prepare for a romantic dinner, they share tender moments, revealing the unique beauty of their mutant union.
