In recent times it has been quite modern to prevent the Mini-chinese in professional play, and as such, creating a new Fuseki with as much depth as the Chinese fusekis. (I do however not have the level to explain anything in detail, and since it is quite new there are still very limited material on this fuseki).
The fuseki was invented in Korea and has become more and more popular in recent years. The name of the fuseki was given because the man who invented this choose to dedicate the name to a chinese girl he had fallen in love with. (if you believe such stories that is). No matter the reason for the name, in Chinese, Lei means a flowerbud, bearing a message of beauty from this fuseki.
