Your #6, I kinda get a hint that Eugene loves her from the first life, because whenever she tries to reminisce her memories with eugene, he's always there for her, like on the sideline, always there, though they never talk but that serene feeling that she felt when they are alone is an enough hint ( atleast for me) that she felt the same way, also on the first chapter, I guess ? When eugene peeked at her room, his eyes looked hurt . unlike the other brothers who is annoyed.

I like all your facts(づ ̄ ³ ̄)づ some people are very skeptical about the ship, but I’m okay with it. Yes, they are siblings by law, but not by blood. Plus, it’s not like Hari spent her whole childhood with Eugene. She grew up in the Johanes household. So I get confused as to why people say she grew up with Eugene..

Exactly!She literally only lived with him for 2 years (out of which the 1st year he wouldn't even accept her lol) and they they were seperated for 6 years... Also the way Eugene always blushed around her and even said that he can't accept her as his sister (early on) kinda gave it away for me. There is most likely something more going on...

Now that you mention it... Yes it might be harder for Hari since she has her past memories. However in her past life they weren't even close... As you said the time line and the events have changed so much that I honestly wouldn't be surprised if she returned his feelings. As for Eugene Idk about his past life but he definitely has a crush on her now Anyways, I guess we will see where it's headed soon enough.

I'm really happy that you all agree with me!! Yes for Hari it could be a little difficult and unexpected, but in the novel she had feeling for him as well, she just never realized. Also Hari and Eugene were close in her past life, but only when they became adults, and even then their relationship was more than platonic, it's just they both did not want to go there. In this life Eugene changed and I think he loved her too much to try and contain himself. Also these are two totally different timelines as you all said, so it's invalid to compare them anymore. Just like how everything changed in The Abandoned Empress because she herself changed.
WARNING, LONG POST AHEAD, SORRY !!
So I decided to make a post regarding this issue as well. I honestly feel like we shouldn't hate on Eugene and Hari ship because:
1. It isn't incest, they are not related by blood, so it's not morally wrong and their children won't be affected.
2. Hari may have looked like his sister in the past, but she has grown up since then and she doesn't resemble the little child she was before (appearance-wise), so I don't think that is a problem anymore.
3. When we think about it, she spent 2-3 years with the Ernst and Eugene, BUT spent 4 years with Vastias and Johanes, so most of her grow up period and her transitioning from a child into a young lady she spent with Johanes, so by that logic they could view each other as siblings or close family friends (it's different from the past when she didn't meet him until she was engaged to him).
4. I don't think Eugene ever viewed her as just family, she is really dear to him, but they are not blood related and I don't think he really viewed her as a sister, more as a close friend. They both did not fall in love with each other until much later, aka from this point in the manga when they are both much more mature and meet each other again after years. So I don't know why much hate for a ship that is only just starting, since they didn't have any REAL romantic moments so far.
5.I also don't think Hari viewed him as a brother, or maybe in the beginning, because if we go back to the beginning where she described how they got along, it seemed like she also liked him, but kinda blocked her brain from thinking in that direction because he was her "brother". This part is explained in the novel and hopefully will be explained in the manhwa as well, and the explanation was that she loved Eugene in her first life but, as I said, didn't allow herself to think in that direction.
6. And this point is the most important to me, Eugene loved her in his first life as well. He loved her enough to find a good husband and give her away, but he couldn't walk her down the aisle and give her away himself. He suffered so much in both his last and this life and I feel like he deserves to be happy and be with the one he loves.
Now this story is not for everyone and it touches on a little "controversial topic" per sey, but this is ONLY the start of the story and their love, so I feel like we shouldn't hate and judge them, but actually enjoy the story and judge it in the end when we get all the pieces and their romantic moments and see how they work together.
