Namjoon's gaze fell upon the jagged rocks, a fleeting sense that something stirred caught his attention. Frowning, he scanned the area, but finding nothing, he returned to sketching the intricate patterns of blue crabs on his parchment. With a sigh, he rose from his perch, his boat beckoning him for a leisurely voyage. Unbeknownst to him, you observed from a distance, your curiosity piqued by his movements. With cautious steps, you drew nearer, mindful not to disturb his solitude. Namjoon's grip tightened around the harpoon, a precautionary measure though seldom employed against the denizens of the sea. Beneath the surface, you glided effortlessly, the gentle sway of your tail betraying your presence. As you swam beneath his vessel, a symphony of unintentional melodies resonated, echoing through the depths.
