It was a little past midnight. Lee Bada walked past the convenience store in front of the harbor toward the beach. Even though it was summer, the night breeze was quite cold. She hadn't checked how long she had been walking since leaving home or even what time it was. She just wanted to get as far away from the house as possible.

There was no one on the beach. At least, that was what Bada thought. Until she spotted a single head of black hair moving through the waves in the distance.

After a long while, the male student who emerged from the water picked up a towel he had left on the sand. Then, his eyes met Bada's.
