It is true that Cosette is the Duke's daughter from her 1st wife. Furing the time when his wife was chased out of the Parvis family she was pregnant. When the marques (Keira's maternal family) knows about it they pay to assassinate them. During that process Duje's lover (1st wife) made a deal with the demon in order to revive the baby Cosette but instead of granting that wish the demon coveted Cosette's body and used it for her own. That is the reason why the current Cosette looks like the Duke.
If you're gonna ask if Keira is the only Parvis lady. The answer is YES since the real Cosette is dead.
The real Cosette is born of mutual love from her Parents.
yeah i heard that there's no ml in this. and the duke turn back time to save himself.
Guys. I have read the spoilers.
There is no Male lead. At the end, she and her brother will travel leaving their father alone.
Also the Cosette that we have here is a demon, the baby Cosette died and her body was taken over by the 'Disaster'
The other person who contracted the magician (i think his name was Claude?) to return back time was the Duke. On the first timeline, since the true spirit user died, the disaster was able to manifest and destroy their country. That's when the Duke found out that the daughter he killed was the real spirit user
yall can cuss in y'all's language in the comments

HIS FATHER IS THE WORST, NOT ONLY HE DIDN'T GIVE A FUCK ABOUT HER DAUGHTER SINCE SHE WAS A BABY, HE'S FUCKING STUPID, I WILL NEVER.EVER.LIKE.HIM.

The fact the he casually ordered his daughter to be killed just horrible. I will never forgive him. I hate him more than i hatr cosset bcs he was her own father. Someone she live with her entire life. Someone who want his love to the point harming herself. AND FOR WHAT? HE DAD DONT EVEN BAT AN EYELASHED WHEN SHE DIED. WHEN HE-
He didnt even tried to save her...
I also didnt get it why the fuxk he started to care when she finally get her shit all together. When she finally can ditch her asshat dad.. When she finally breath and start living her life freely..
Motherfucker i sincerly hope you die.
At the end of your life, i hope you suffer
I hope you feel regret and feel the loneliness suffocating you from the inside.

I HOPE HE FUCKING ROT IN HELL
NOT JUST ONE TIME, IT'S FUCKING TWO LIFES HE DITCHES ON HIS CHILD
FUCK
HE'S A DICKHEAD
I HOPE I CAN TORTURE HIM TO DEATH AND THEN MAKE HIM ALIVE AND TORTURE HIM AGAIN
HE'S LIKE PEOPLE LIKE " YOU'RE THE FUCKING FIRST ONE TO TREAT ME LIKE THIS" WHEN HIS DAUGHTER IGNORE HIM
AND HERE I THOUGHT I CAN LIKE HIM
THAT PISS OF SHIT
AND I READ THE SPOILER HE'S THE ONE WHO MAKE CLAUDE TURNED BACK TIME BECAUSE HE KILLED OUR MC IN HER FIEST LIFE BUT TURNED OUT SHE'S THE TRUE SPIRIT USER
DON'T LET ME CUT HIM TO 18 POECES AND MAKE SOUP OUTTA HIM (╬ ̄皿 ̄)凸

how abt we turned back time when the brother still a baby and teach him common sense and martial arts? it's really killing me when he don't know a shit and overestimate himself.

The man just learned that his wife has been scheming and poisoning his daughter without his knowledge for years. If he thinks his son might have inherited her way of thinking, then it’s not enough for me to brush it of as “he probably heard that from his mother.” The fact is that the FL’s brother might be instinctively trying to preserve his seat as future headmaster and it does take a subtle amount of cunning smarts for that.
If he becomes headmaster, then there shouldn’t be a question as to whether his sister could take the position away from him. In some clans, even if the woman gets married, the man will move in into their clans because the woman’s clan is of higher status (like it’s the case with Dang and Eon). However if that’s the case in that situation and his sister stays within the Dang territory, it might call into question his authority, like when different lords or people in power choose sides despite there being a clear leader.
can't wait!!! guess i will dropped this and pick it up on 2022 so i can feel satisfied!
