That did not take long for President Yoon to enter negative territory for his approval rating:

President Yoon Suk-yeol’s disapproval rating surpassed his approval rating in a poll released Sunday.
The survey by Research View, conducted on 1,000 South Koreans aged 18 or over from last Tuesday to Thursday, was the latest in a series of national polls, in which those giving a negative assessment of Yoon’s performance outnumbered those who were bullish on the president.
This poll was conducted while Yoon was visiting Spain for the North Atlantic Treaty Organization (NATO) summit, his first overseas trip since taking office in May.
According to Research View, 51 percent of the polled said Yoon has been doing an inadequate job as president, while 45 percent said he is handling state affairs well.

You can read more at the link, but according to the article a month ago his approval rating was at 53%. The only thing I can conclude is that voters are now holding him responsible for inflation and economic woes and going to NATO summits is not addressing these issues.
