Epiphyllum in Love

As technology evolves, memories became controllable. Subsequently, the soul becomes a commodity. Every memory has a price and can be bought and sold. The main character is a person who has sold his memory. But there is always a girl in his mind who cannot be forgotten. Who is this girl named "Yin"? What was the past between her and "me"? When all the memories are discarded, What should we do to find our true selves? Should we die with a beautiful fantasy? Or should we search for the sad memories of her? The final chapter of the #workshop short-story trilogy.
