Revenge of Reborn Princess

It's a similar story about revenge. Both leads are aware of their circumstances. Female lead is seeking revenge and male lead is supporting her.

Both are mini dramas in which the FLs die and are reborn in the past, becoming involved with the ML who, unknown to them, is also reborn and has been protecting the FL all along.

In both of them, the FL was wronged in the past, and after she's killed, she awakes before everything happened and wants to take revenge, she does take it seriously. Also, the ML is a prince and wants to help her no matter what, he falls first.

Every time the main leads die, a magical jade pendant helps them to come back in time.
In both, the ML is a prince and the FL is strong.
