Spoilers:
This is superlong lol so forgive me
The spoilers that I've read didn't really explain what happened to this investigation from the empress right now, I don't know if I missed it or what but here is what I've read.
The ML slowly falls in love with the MC as what is shown right now and the way he blushes. I think it happened in the middle part of the story that he confesses for his feelings to the MC and the MC also did the same but after that one servant rushed up to the emperor and told him that Lin is sick and is asking for him to come over. Maybe because the emperor still hold his frienship with Lin, he actually did left the MC's to go to Lin but before he did the empress stopped him because she somehow knew that she is going leave her the empress vessel due to some bad things that will happen and that is she will get assassinated. It did really happened after he left, the empress got kidnapped and was beat up however on the emperor side, Lin was actually not sick and greeted him quite lively. The ML/emperor asked why she lied to him when she never did that before. On this one Lin might have lied to him because she got jealous of the affection that the emperor showed the empress which was directed to her in the past. While they were talking a servant came and reported that the Empress got kidnapped. He rushed to the empress but he was too late and found her sprawled out beaten, with her blood covering her body. That event changed the emperor, he was traumatized and ruled as a tyrant for two years.
The truth is when the empress experienced the assassination the MC's soul transferred to another body. The body she transferred was actually a male based on what I read. I don't know how but that's how it goes on the spoilers. The body that she transferred to has something to do with that Assassination Group that has also attempted to assassinate the empress which was her former vessel. At this point the group has a plan to kill the emperor that they sent some people to the palace and she was one of them. She was assigned a position which is fairly close to emperor, I can't remember what is it. They say habits die hard so she sustains them to the point that the emperor was reminded of his beloved empress whenever he looked at him(MC but on a male's body). Gradually he develops affection to him because of his regret that he wasn't able to show the love he had for the MC's empress vessel. To the emperor, the male vessel of the MC who reminded him of the person he loved was kind of I guess another person or object he want to treasure or direct his affection due to the empress absence.The person who spoiled this said that there's actually a hint of shounen ai to this part because the emperor liked the mc but having a male appearance. The emperor is also very vocal about his like to the MC's new vessel. Rumors filled the palace that the emperor have fallen to a guy, so Lin used some underhanded tactics to blame something to MC. I think it's the assassination of the emperor that was blamed to the MC but I can't remember if Lin was part of The Assassin's Group. The MC was imprisoned for this event. After she was imprisoned and the emperor visited her, he can't accept that he betrayed him because he actually kind of believe the accusations but at the same time can't because his affection towards him. At this time the MC confesses about the assassination plan towards the Emperor(I dont know if she told him she was the empress) but one of the guards that is listening to them was part of the group. When the emperor left the MC's second vessel was killed I guess. After that happened the emperor heard the news and quickly run to the mc's side but was again greeted by a bloody body of someone he hold dear. He was reminded of empress when he saw this scene and was further traumatized, I can't recall what happened next.
Upon the death of the second vessel the MC was given three choices: return to her original body, second the empress body and the third is I can't remember. She chooses to return to the empress body because she wants to be with the emperor I guess.
I can't recall the other parts on the spoiler lol but they lived a happy life after this I guess lol and at further part the emperor knew that she was also the man.
At the end of the part the emperor kissed the forehead I think and said something but I can't also remember because my memory is betraying me. Lol
