Anna slowly woke up and saw her lover standing by the window, looking at the bright sunshine outside.
She tiptoed towards him and gently leaned against his back, "What's the matter? Have you noticed the sunlight fading again?"
"No, look at the sea over there, we've already reached the East Sea."
Resting her head on Charles' shoulder, Anna followed his pointing finger and noticed a peculiar scene on the sea surface—the dark green water was miraculously juxtaposed with deep brown water.
The waters that should have merged with each other remained quietly in their places, like two fields.
"It's truly magical. The waters of the East Sea are different from those in other places."
"I've read online before that this situation usually occurs only when there is a difference in density, like the clash of freshwater and seawater at the mouth of a river."
"Either the salt content of the East Sea is much higher, or much lower than in other areas."
