The Korean musical 'You & I' opened in London on the 20th, marking its entry into the British stage. The work tells the story of a husband who lives with an artificial intelligence based on data from his deceased wife, exploring the universal emotions of love and memory. Translated into English after two years of localization work, it was tested for audience response at the Edinburgh Fringe Festival. This performance, cast with local actors, signifies the rebirth of Korean works adapted to the British system.
