I am looking for a manhwa.
Its a Chinese manhwa. The emperor and the consort are childhood friends but for some reason she became his consort and they both act like they hate each other in front of everyone and one day the palace get attacked by traitors feom inside the palace staff and she take an arrow in his stead to save him and die. She comes back to life in different body to find out they blamed her for the attack calling her traitor and held her family captive. She looks like her past self but they all know the past her died so they dont know its her. She becomes the bodyguard for the emperor who pretends to have lost his memory after yhe attack and believe the ones around him that says she was the traitor and she fed him poison. While in truth she gave him the antidote before dying protecting him. So she starts to investigate to save her family and protect the emperor whome she loves from danger again
