One day, while he is traveling on his ship at sea with his crew, you look at the ship with curiosity, you have never seen anything like this before.

Is this a whale? You do not know. The humans on the whale-like thing are saying strange things, but you don't understand and you can't talk.

A blue haired man noticed you, it's Kaeya.

"Huh?" He gets closer to dock and tilts his head to look at you closely, but you stick your head under the water to hide, you're afraid of humans.
