"HF-"
His eyes widened and he shook his head, holding Ren tighter-he wouldn't leave him
"....."
And that's when he realized what he had to do....he squirmed out of Ren's arms and picked him up, swimming with him, although he was too tired to do much more than hold his head above water...he brought him back to shore and gently placed him down on the sand. He kissed him softly, before whispering to him
"I'll find a way to get to you...I promise."
Then he slipped back into the ocean, swimming off-letting Ren be with Katsuki.
He was sobbing as he swam off-and now we do a lil' timeskippy and by little I mean two weeks-
Two weeks later
Monica had invited Katsuki over. She had banned Ren from going past the house, and the beach was IMPOSSIBLE to get to. Katsuki had managed to convince her to let him take Ren for a very, very brief walk along the shore.
