He was so happy to see it that he rejoiced as he saw the vast body of water.

Exhausted of his vigorous actions, he decided to rest on the shore.

But as he opened his eyes he went back to the reality that the sea was gone for a very long time.

It was 12 years ago when the see was taken using a device called, Sea Sphere.

It was taken for preservation. Saving it from the danger of pollution.

To keep cleaning the world to persuade those who took it to bring it back.

As he was finishing up his work, one normal day, something rolled to him hitting his foot.

It was a Sea Sphere!

Overwhelmed by the knowledge of having the sea in the palm of his hands, he took the device away from it's keepers.

Outrunning his pursuers, he took refuge in his best friend, Claire's house.

Claire was shocked with what Bong brought to her house.

Bong lied about where he took it but before Claire could speak, her father, Leonardo appeared asking about the device.

Bong was surprised to find out, that Leonardo is the creator of Sea Sphere.

Bong and Leonardo argued about the return of the sea.

Leonardo told Bong that he did what's best for the sea and saved it from the dangers of humanity.

But Bong told him that he doesn't hold the right to impose that kind of judgement to humanity

and that only God can take away something from them and pass judgement.

Leonardo, actually wanted to return the sea for a very long time

and is waiting for someone like Bong to persuade him that humanity still cares for the sea.

In the end, Leonardo decided to return the sea, 

 believing like Bong that the people learned their lesson and that this time 

they will show much care for nature's greatest treasure; that is the sea.
