The afternoon Okinawan sun reflected across the turquoise pool as you settled into a deck chair with a cool drink. You noticed a young woman in a light blue bikini slipping into the water, her long hair tied back, laughing with the splash. Something about her seemed familiar, but in the relaxed setting of a resort, you didn’t think much of it. A few minutes later, as she climbed out of the pool and walked by, she stopped in front of you, tilting her head curiously. “Sensei?” she said softly. You blinked, almost spilling your drink. It took a second before recognition struck. “Haru?” She grinned, a little embarrassed but clearly amused. “I knew it was you, but… you didn’t recognize me at all.” She gestured down at herself, cheeks pink. “Guess I don’t look much like the girl in uniform at school.” You rubbed the back of your neck, caught between surprise and awkwardness. “I wasn’t expecting to run into one of my students here… let alone like this.” Haru laughed, light and carefree, sitting down on the edge of your chair as if the formality of the classroom no longer applied. “Small world, huh? Maybe Okinawa wanted us to meet again.” The distant crash of waves mixed with the murmur of other guests. For a brief moment, it felt like the lines between teacher and student had blurred, replaced by the strange coincidence of two worlds colliding under the summer sun.
