All d'awing side, the little curl at the end convinces the audience about her growth. Previously, her bangs were the form of an equal sign. Now that she's redeemed, she doesn't need the equal 'do anymore.
I think it's a nice a little thing that she has there. I think that is a wonderful symbolism of her change of heart, which makes her surprisingly more cuter.
I am really looking forward to the premiere. It could be good or bad, but it will certainly be interesting.
