Probably a combination of otome game reincarnation magics, and the power of friendship.Huh? Wait, how did they recognize each other?
I double-checked on that a few times, because she said "bad friend," and then 3 pages later she's her "best friend."MC: she's a bad friend
the friend: reality and fiction are different, we are both reincarnators and I like the real guy, even if he was your favorite character he is not like that
MC: shit, maybe she was a brother
Fr, she can actually distinguish the difference between reality and fiction and see how the sadistic prince would be a terrible person to have as a husband, even if he's her favorite character. It's one thing to enjoy it as an observer, but it's totally different once you're in one of the characters' shoes.the heroine is the actual smart one
