Too many Netflix features about Hospital Playlist https://twitter.com/HosPlayPH/status/1379389634266984456?s=19
I think they already started and the filming is still on going. There are some indirect posts already that's going around specially on Twitter like coffee truck pictures and just awhile back a Jo Jung Suk fanclub just posted about the coffee truck they sent on the site. It was sent late Feb but guess they were only allowed to post about it now. By the looks of it, looks like we are about to enter the promo period for Season 2.
