After MC possesses empresses body she meets adoptive brother. He said that her fated pair mark was half faded but thanks to a shaman it should have returned now. What does MC do? She compleatly ignores what he said and thinks that she has a half a mark (she actually has a full mark now) and constantly hides it. All the problems in these 63 chapters would have been resolved if she simply looked in mirror at her back (mark is on butt) to see how it looks like, but she never does that. Only after everyone says that she is the fated one she finally checks it out.

She doesn't have/create a plan and just goes with the flow (Lies and instantly gets found out. Drugs emperor and hides from him while thinking that there won't be any consequences (seriously, she was surprised that knights were looking for her)). She can command/talk to birds but doesn't send a message (even when she constantly says how she needs to save the kingdom). She always wants to get away but when she gets a chance to teleport away, she just doesn't do that. Her maid was blackmailing her, and her solution was to simply kick her out what obviously backfires.

The MC is some type of saint who can see the future. While tired to protect/warn the emperor that he was to be killed by his brother Prince in the near by future, unfortunately, her so-called trustworthy person kills her with that prince. After dying, she possesses the evil/spoiled Queen's body.

Now to save herself from the bad fate of the original queen, she plans to first try to protect the Emperor from that prince, And then divorce him (Emperor), more than getting justice for herself.
