"It's too hot out here," Kaoru complained from under the umbrella, lying on the lounge chair while fanning himself with his fan. Even though he was only wearing a summer yukata, the heat was unbearable. He was reluctant to enter the sea and risk getting covered in sand and seaweed or sunburned.

In the distance, he spotted his friends, both adults and teenagers, playing in the water. He had only agreed to come for their sake, although the scent of the sea and the distant sound of waves were indeed relaxing.
