What's this about han seori and FMC not being biologically related.??! What.?

I thought mc said that because she isn't originally from this world?

Spoiler



















Remember that

























Not same father dif mother, the og Fl mother drugged the father and r@ped him
while he was engaged to our Fl mom

But that makes them having same father. What.?

Spoiler.




Han Sori and the current fl's brother aren't related by blood. He's adopted. It's not really a spoiler because this information is from a previous chapter, but it is a spoiler for people who haven't gotten that far.

Though, I'm pretty sure our current fl just meant that since she isn't originally from that world, she isn't related to that hot mess of a woman.

It's a mistranslation, the pronouns are jumbled in multiple places in this chapter. She meant that her brother is not blood related to Han Seori
FL and Seori are half sisters
