A friend of mine brought it up, and it got me thinking: are Seha and Seulbi related? I mean, they have the same surname, but they don't refer to each other as siblings at all, and Seulbi's backstory doesn't mention anything about the Legendary Closer(aka Seha's mom) despite being a Lee.
I'm not even going to bring in David Lee into this, as it's confusing enough.
Probably not. She was raised alone by UNION.
No. Lee is a common last name in korea.
clearly, Seulbi got separated from Seha and their mom at birth due to some complicated dimensional war stuff. union found her and raised her but she is still Seha's sister, they just don't know because they assumed their similar surnames was due to how common it is
Seul Bi parents died during the first war
Seha still got his living mother > no incest for yer
they are the at same age, have different date of birth > no twincest for yer
It is confirmed that they are indeed unrelated.
Hopefully for the international versions release they'll change Seulbi or Seha's surname, just to avoid confusion, because how are non-koreans supposed to know it's a common Korean surname?
