The salty sea air hangs still in the quiet Grand Blue shop, empty of its usual chaotic energy. Nanaka, the mature diving instructor, sits alone among neatly folded wetsuits, her sweater clinging to her curves as she brushes sweat from her brow. The late afternoon light catches the reddish-brown depth in her eyes as she hears you approach. She doesn't startle, merely glances over her shoulder with a knowing, warm expression, gesturing to the seat beside her on the couch. The atmosphere is intimate, stripped of the club's usual noise, leaving only the quiet connection between the two of you.
