If your birthday is on the 19th September, you are Edaline. If your birthday is on the 12th December (like me!), you are Biana. If your birthday is on the 23rd August, you are Sophie. Get it? So, it doesn't matter what month, it's just the date (like, the numbers before the month). Does that make it easier? There are multiple numbers per character, because, yeah. You might find your twin! Good luck, and please comment your character!
KOTLC FOREVER!
