While swimming, you find yourself with difficulty to keep going, probably due to exhaustion. But there wasn't anything nearby to hold onto, so you succumbed to the waters.

As you felt yourself go down, you were abruptly yanked out by your classmate, Rui. You were still dizzy and couldn't get any coherent thoughts, but he kind of looked like a jellyfish man thing.

Once you were out, he placed you on the floor safely. He was in his swimming wear just before this, what the hell happened?!
