After a moon jellyfish died in the aquarium due to a prank caused by tourists, which caused an imbalance in the salinity of the water, it traveled through time and became the vase actress Su Yue who was black on the Internet.
She has no heart, does not understand the ways of the world, and can only be in a daze and shine. The manager collapsed because she "can't understand human speech", but she unexpectedly gained fans with her "motionless" variety show performance. She doesn't know what lies, malice, and flattery are, but she resolves the scandal time and time again in the most straightforward way.
Film industry heir Gu Shen noticed her abnormality due to his background in marine biology. From curiosity to protection, from exploration to affection, he taught her what "missing" is and what "preference" is.
But her body began to count down to "turning back into a jellyfish." She must choose between "returning to the sea" and "staying as a human being."
In the end, she chose to stay - not for love, but for "the person I want to be."
When she shined at the award ceremony, when she said in the live broadcast, "I am not a human being in your definition, but I will be sad, miss you, and want to protect someone" - she finally has a heart.
Concept: She was just floating. Later, I had a direction I wanted to go in.
