From what I see the FL has not lived past her twenties in all her lives???(I'm guessing) and it seems more realistic that she experienced all sorts of pain and betrayal 7 times before becoming strong. I mean she literally went from being the definition of dumb and naive to someone you seriously don't wanna mess with. If it were me I think it would take atleast 3 to 4 lifetimes to become like become the way she is right now so I think it makes sense she lived and died so many times.
Those characters in extra 7 the waiter and the actor are the same people from the omegaverse story the author is planning on creating!!!!!!
