This is lovely! I enjoy how rich the descriptions are (thank you for taking advantage of the setting to deliver damp skin and sand-caked legs and dripping water and all the other sumptuous hallmarks of a beach scene -- also, eldritch beauty!Fuji, yesss), and how well you incorporated the imagery of the song. The emotional dynamic is also sweet and playful in a way that feels just right for Taka and Fuji. Thank you so much for filling my prompt!
