You mean leander and herold. Legend has it that leander and Herod are husband and wife, separated by the Dadani Strait which separates Eurasia. Leander swims across the channel every night to meet his girlfriend Herod, who lights a torch on the shore to guide him. One day, the torch in herold was extinguished by a storm, and leander was lost in the strait. When the sun rose the next day, the waves washed leander's body ashore. Herod saw leander's body and jumped into the sea. In addition, the prototype of the flower on the other side is Heluo.
