Based on the summary I thought FL meant that her rival would be the her from her 18th life since that her is the person ML loves. “The biggest rival of my 19th life is my 18th?”
*romance rival
Nope. I don't know about 2nd FL. But from what I saw from raw....

Seems like the little sister love the black hair guy (ML's friend)

I think there is going to be a second female lead and I think it’s the little sister of her 18th life......I really hope not though
