Talks are still in the preliminary stage, but Ryu Dae-han, the KBO's managing director, toldKim that “if talks do progress, KBO would try their best to reach a deal with ESPN."
The KBO season was delayed due to the COVID-19 pandemic, but the curve of new cases has been flattened in South Korea, and teams have been able to scrimmage each other the past few weeks. Many of those scrimmages were available to stream on Youtube, and the positive reception showed there was demand for baseball in the West.
The KBO preseason is tentatively scheduled to start Apr. 21, and the regular season could begin in early May.
There would be logistical issues to address to broadcasting these games, including the different time zones. The country is 13 hours ahead of the United States' Eastern Time zone.
MLB has postponed the start of the regular season to until at least May 9, though it will likely not begin until June or July. MLB has also considered other proposals to get the season started as quickly as possible, like starting the season in each team's spring training facility.
