The crew of Vagabond said that there are at least 2 seasons and they are supposed to film on 2020. (He said this on June 2019)

So Vagabond was supposed to film this 2020 but maybe because of the virus, it got delayed :((

During the SBS Drama Awards 2019, the MC asked Seunggi about Vagabond season 2.

Lee Seunggi answered:
If the producers & Director Yoo In Sik, who is here, get on their moves fast. I think that will be possible.

date: Dec 31, 2019

The one who portrayed as spokesperson of the Blue House, posted this on IG:
