Swimming through the icy water, Shinsuke was beginning to run out of breath.
Although the presence of the two rays of light following him through the water reassured him, he still could not find the girl whose hand he had seen a few minutes earlier.
The more the seconds passed, and the more he felt that he also started to lose his strength.
It was cold, he was completely soaked with only his head above water; and was literally the only person crazy enough to throw himself into the river without waiting for the river patrol.
He was almost regretting diving in, when, out of the corner of his eye, he saw a hand rise above the water again. The girl was still alive, and seemed to be struggling to stay afloat.
Without hesitating a second more, Shinsuke let himself be carried by the current to join her while floating, and swam only on the last meters to rectify his trajectory.
