There may be two reasons why Lee Jung Hyun is not so popular now.

For many years, it has been focusing on overseas markets, ignoring South Korea.

There is also that she is the lowest-key of the three, usually only appearing during the album promotion period, but her status can't be shaken by anyone, and there are many classics! Now Lee Jong-hyun's comeback is not to surpass others, but to surpass himself before.
