Actually she said Orphanage* if I am right, it was a reference to a scene when they were little, Jenna Unnie said…
if my theory is correct and will have a Season 2, then the setting might be Seulgi going back to where she came from to practice medicine in the orphanage like in the webtoon
Season 2 it is, jay's father was caught but freed, jay is alive but hiding, there is still also a lot of source material if they want to adapt the webtoon, like Jay's fiance, Seulgi going back to where she came from. I mean, there is a lot options and possibilities
