It seems inevitable with the constant nuclear threats from North Korea plus the growing militarism of the Chinese that the Korean public would want its own nukes to defend itself with:

There has long been a desire among South Koreans for domestic nuclear weapons capability, but a poll shows that in the face of North Korea’s nuclear ambitions and an assertive China, that view has ballooned to more than 70 percent of the population — most of whom want to go nuclear even when the potential drawbacks are explained.
The poll, released Tuesday by the Chicago Council on Global Affairs, found robust support for nuclear weapons in South Korea: South Koreans want nuclear weapons even when they feel confident about the country’s alliance with the United States and about the strength of their own military. And those who support nuclear weapons now see a level of prestige associated with them.

You wouldn’t know that from past Korean media articles that make it sound like a Japanese invasion of Dokdo is ready to happen at any minute.
