She’s also cursed ?
spoilers:
Bro was just brainwashed by a black magician, which made him not care about her.
How are they going to reverse the brainwashing?
I marked the part that answers your question ٩(๑❛ᴗ❛๑)۶
After Eristella disappeared, the atmosphere of the Imperial Palace changed.
Because of his brother's sudden change, Eristella and Heimrich thought that the emperor was connected with black magic.
Pinpoints: The Majesty's official schedule has been significantly reduced. Even if he attends, he leaves early. His Majesty the Emperor seems to have changed a bit. Although the emperor openly hated Eristella, he was not as secluded as he is now.
Eristella got worried and wanted to check up on his condition, hence why Heinrich and Eristella went to a charity event, which the emperor could not be absent from.
When Eristella saw him, his eyes were the first thing that caught her attention; they showed he couldn't sleep properly. Above all, the pale, ghastly skin indicated his condition was not good by any means.´
After the event ended, she turned to her human form and followed him to the garden. While hiding she saw someone brainwashing him.
She couldn't do anything and was mad since when they were children, she proudly said: "When Brother becomes emperor later, i will become so strong that no one can touch you!
Until six months ago, when Eristella was alive and well, there was no strange signs from the emperor.
It was only after they were convinced of Eristella's death that they began to influence the emperor in earnest. It was Marquis Brandon Lateran who joined hands with black magicians.
The siblings had a great relationship but when the black mage put her into a state where she's stuck in her memories, one memory shows that when when's she was 15, starting from summer there was a change between the loving siblings.
The current emperor grew cold as if he was gradually getting tired of Eristella's behavior, and even refused the meals or leisure time they usually spent together.
She realized he didn't hate her because of her destiny of not being loved by anyone, but because of the brainwashing.
Answer to your question:
-----------------------After escaping those memories, Eristella caught the black magician who infiltrated the palace: She was the closest to the emperor. The maid who brings washing water every day and night.
After kicking her ass, Eristella ran to her brother.
Bro was on the verge of collapse. Heimrich saved him just in time.
Traces of black magic remained on the emperor's body. Dark red spots were everywhere, and his fingernails were stained black.
These traces that had been suppressed while being dominated until now were revealed all over the body as soon as the brainwashing was released. Now that he's been freed from brainwashing, any traces left will disappear over time.
Bro was unconscious for a long time, Eristella was always by his side. One time he woke up, proceeded by calling the fox Eristella, and then passed out again.
Time passed, on one night he woke up again calling her name and thanking that she's alive.-----------------------------------------
Eristella cried a lot, she resembled a kid and the two men (Heimrich and bro) panicked, not knowing what to do since she'd never been like that.
She then demanded her brother to soothe her by patting her back.
Bro promised from now on to be with her no matter what and did a pinky promise.
Bro knew of the existence of black wizards before he was brainwashed. He discovered it when he was 19-years-old and still had a good friendship with Eristella.
Bro said she's not alone anymore and that he awaits the day they'll live together once again.
When Eristella and Heimrich went back to the duchy, the emperor sent a silly letter that shook Heimrich, since who knew that the emperor had such a side to him in his point of view.
Woooow! I’m looking forward to the manhwa version. The reunion must be such a scene! Thank you so much for the spoiler! ヾ(☆▽☆)
Same here, and you're most welcome! (๑•ㅂ•)و✧
I'm pretty sure the said brother is on clouds because she is gone as he was literally yawning like others during her funeral, also sure that he might have a inferiority complex.
