I guess all of them have unfinished business in this world, so they got a second chance to get things right. For Eugene and Cecil,they needed to know the truth, get closure and a happy ending, even if they don't get to be together in this life. And for the butler, it was punishment and an understanding that what he did was wrong. That he needlessly destroyed the lives of at least 3 people and made many more go to their graves with regrets.

How come they are already to be engaged? Maybe we misunderstood something? Was there a problem in translation? Here is what I think happened:
So back in chapter 20 Ares agreed to help her in any shape or form as long as she agreed to be his fake fianceé and help him gather intel inside the palace to allow him to find this item. An obvious lie, as there is no item and he was just looking for a believable excuse to make her his. And is most certainly never letting her go. But I digress. ╮( ̄▽ ̄)╭
In chapter 36 they re-start their negotiations. Alicia says she doesn't want to take advantage of Ares and would rather get a job as his advisor. And Ares keeps arguing that she doesn't need to go through all of that, as long as she becomes his fianceé he would do anything for her. So how come they are now planing their engagement?
Maybe it was the translation, maybe it was just bad writing or even that she had a change of heart that will be explained in the next chapters. In case of the 2 first options, it might have been that she never said no to his proposal, but in order not to take advantage of him she will ALSO become the Black Sun's advisor - which would grant her a very good salary, and money is something she desperately needs right now.
I guess we'll have to wait and see what will happen next. Either way it seems like we are getting closer to the blessed moment where the annoying princess Edith realizes that Ares will never look her way because his heart (and other body parts LOL) already belongs to Alicia (๑•ㅂ•)و✧

Like she said in the last chapter, suddenly getting engaged to her brother's hero was also going to be a problem. The little emperor is prone to jealousy where Alicia is concerned, which is understandable since she was his parental figure and only family member for so long - as we can see in his conversation with the maid in chapter 46. Alicia needs to give her brother some time for him to get used to the idea of her dating. Which is why she asked Ares to delay the engagement and to act like a couple in love in front of her brother. I guess she is hoping that her brother will accept it easier if he sees that she is happy and has some time to get to know Ares outside of their usual dynamic of emperor and war hero.

I guess their deal to fake an engagement to be married was never off, what was out of question was her relying on that and only that to get his help in gathering the power and money she needs to free Kai from his aristocratic manipulators, without giving Ares anything in return... Her becoming his advisor is a way to repay him.

This is my interpretation of what happened:
In chapter 20, he proposes to be in a “fake” engagement, but she rejects his offer (even though he said it was “only to have an informant in the palace”). He still sends stuff over to her later in the story as a means of trying to make their engagement real, but she rejects all the stuff (and thus the pink diamond is not seen or worn at the Victory Celebration). Now, she is bringing up negotiations to be in a fake engagement for an entirely different reason: to stop the rumors of her going out with other men and to put her brother’s mind at ease. Notice that in chapter 20 and the other chapter that she never says yes to his proposals. I just read it through from the beginning through these last couple days (had never read it until now), so my memory is pretty fresh.

To both you and Artemis Fire: Okay NOW this all makes freaking sense! It was the wording that really confused me. If she refused the engagement because she was worried about her brother why did that suddenly change to her ACCEPTING the engagement because she was worried about him? Same if she accepted the engagement only because she was no longer worried about him, why did she suddenly become unworried about him? But now those questions are answered. Thank you both!

People are complaining that Hari is acting like a kid, but I don't think she is.
Acting like a kid in a situation like this, at least to me, would mean to take revenge by using the parents' blatant favoritism to punish the boys again and again until they started avoiding her all together.
There is also a HUGE issue that to me makes it impossible for her to "act like an adult": NOBODY TELLS HER ANYTHING! All she knows is that she was adopted as a replacement for this dead girl.
She knows nothing of the dead girl's relationships with the rest of the family, only assumes that she was very loved. She knows nothing of the mother's mental illness. She doesn't know that the older brother has been forced to grow way too early in order to raise his siblings, even before their parents' death, or how he is punished for his siblings' mistakes. She has no idea that the parents treat the boys differently when she is around and when she isn't.
Going back in time and being a grown up in a kid's body did not make her wiser because she NEVER got to know ANY of the family members. She was treated as an outsider her ENTIRE first life.
How is she supposed to help these people if she doesn't know what's wrong? All she has are her observations. She is trying to give the boys more time with their terrible parents and to make them see that they can't treat her like trash. I honestly can't see what else she could do, considering that she has no power in that house.
So this is a story about a supervillain on the run who accidentally stole the heart of a powerful (and sweet) demon.
