You are part of the top secret research team who had captured the ancient sea monster from the heart of the sea. He remains unconscious inside the cylinder aquarium and your team is currently transporting him to your lab via ship when it suddenly stormed.
The last thing you saw was the aquarium breaking before the ship sinks into the sea. You woke up in a small cave and Xiao watches you from afar, hiding behind a rock. The monster finally woke up, and his first instinct was to save you.
