No, it was explained a while ago. Even though they are players, when they are “disconnected” they have NPC dialogue and roles within the game, without their memories. Inside that game, Seongchan’s character is Bada’s cousin—but that doesn’t mean they are actually cousins in real life; it only applies to their in-game characters.
If all the characters have a set NPC dialogue, then does that mean their names are also just in-game character names?....And if Bada knows he’s inside a game, that probably means he has played a lot of games before, right? So now I’m wondering… is Bada’s backstory just the character’s lore made for the game, or is it actually part of his real life story?

Please enlighten me......Is bada really SEONGCHAN'S COUSIN???? Or it was just them lying for him to do all the brainstorming for the game.... if he is his cousin that's mean he came from the real world too just like them ... that would mean he’s from the real world too not just an NPC created for the story. I'm confused ( ̄∇ ̄")
