7. Cinderella and the Four Knights

8. The Rebel Princess - FL loved and planned to marry 2nd ML before she got an arranged marriage to ML. Then she fell in love with ML and her feelings for 2nd ML changed. Didn't help that 2nd ML did a bunch of bad and crazy stuff trying to win her back. She didn't love him the same way by the end.

9. True Beauty - if you count either of them as 2nd ML, it still works.
