After Dressing up as a Female Supporting Role, I Was Killed by Villains Three Times

Su Wan dresses as a vicious female supporting character and has a simple task - to help the master fall in love with the heroine. Then she was killed by the villain. Three times. The fourth time, she went to him with a knife to settle the score, but found that he did not remember killing her at all. With each reincarnation, his memory will be cleared, and he will only use instinct to stab that sword. But his sword would avoid her right wrist every time. And the scar on her wrist that even she couldn't see was getting hot every time. ——Is she the person he is waiting for? ——It doesn't matter, this time, she wants to find the answer first.
