2-4 weeks delay Before Romeo and Juliet and Chunhyang, there was Seo Dong and Seon Hwa. The fated love between Princess Seon Hwa of the Shilla kingdom and Seo Dong, the future King Mu of the Baekje kingdom, is a classic tale set in Shakespearean lore. It is immortalized in Seo Dong Yo, or "The Ballad of Seo Dong", an old Korean folk song that spread quickly through the palace and the country during the Shilla period.
