You were swimming in the water until your leg got stuck in something and you started to bleed..

It was getting late, there weren't a lot of people left on the beach but you still screamed for help but no one heard it..

After a while you started to drown, you thought it was the last day of your life but! Heizou came and saved you

You wake up in a hospital and your leg was bandaged

"Good morning..your leg got stuck between two rocks, luckily I was there..." he said in a worrying tone
