Her smile is worth a million and her pillbox holds abyss. Travel experiencer Joey heals the world with his most perfect smile, but he swallows antidepressant pills alone every night. Until she completely collapsed in the aquarium and met a beluga whale who comforted her by touching the glass with his fins, and the man behind the whale who was more silent than the deep sea.
Lu Yu is the top beluga whale keeper at the aquarium. He can understand every ups and downs of the whale song, but he is accustomed to being silent towards humans. When Joey requested an interview with a bright professional smile, he only said calmly: "With me, you don't have to smile." This sentence tore apart the perfect disguise she had maintained for twenty-six years.
From then on, the blue aquarium became her most special clinic. He taught her to listen to the breathing of whales, identify the pulse of corals, and wait for the first ray of morning light in the deserted Dolphin Bay at midnight. And she gradually discovered that this seemingly cold man would carefully hold up the injured fry, remember the name of each turtle, and hide the tender past under the old scar on the eyebrow.
When travelers stop wandering and lonely people learn to talk, a prescription written in blue water quietly unfolds: the dosage is the length of the whale song, the course of treatment is the cycle of the tide, and the medicine is the glimmer of light that fits together in each other's broken souls.
This is not a simple love story. This is how two souls floating in their respective deep seas become each other's buoyancy. In the silent whale calls and rippling waves, they learn to coexist with pain tenderly, and live the cracks into the toughest texture in life.
