"Now move your legs. Almost like you're walking-just move your legs through the water..."
"I-I can't-"
He shook his head, holding onto him tighter.
"Hey hey-I'm not letting go of you Ren-just try it..."
"......."
He sighed, then started moving his legs- still holding onto Kai.
"Good-good-you're doing great!"
"O-Okay I'm done-"
He stopped moving his legs, and held onto him.
He laughed a little, kissing his head
"Ok, ok-I'll swim you back to shore."
"Please do.."
He swam him back to shore, setting him down on the sand. By the time they reached it, Ren had fallen asleep in Kai's arms
