Part 2
Big Fish & Begonia
A 16-year-old girl travels to the human world in the form of a dolphin and forms a connection with a human boy.
It is a world within our world, yet unseen by any human, and the beings here control time and tide and the changing of the seasons. On the day Chun turns sixteen, she is transformed into a dolphin to explore the human world. She is rescued from a vortex by a human boy at the cost of his own life. Chun is so moved by the boy's kindness and courage that she decides to give him life again. But to do this, she must protect the boy's soul, a tiny fish, and nurture it to grow. Through adventure and sacrifice, love grows, yet now she must release him back to the sea, back to life in the human world.
