Viki recently added "Winter Sonata" so I decided to send them a request for "The Legend" too since I've never seen it.
I hope since Korean dramas are becoming increasing popular it might be likely some older dramas will be released.

Viki has recently [December 1, 2022] added "Winter Sonata" to their regional selection.
I decided to send a title request form to Viki for "The Legend".

Here a Viki's Title Request form link for anyone that might want to use it.

I think you are correct about Viki. Many if not most of the VIU series are also licensed to Viki.
Also, Viki has season one.

Coming to Netflix in the USA.

Looks like it may be available on Viki. But licensing has not been announced.
