TL1:
*Ines and Carcel marry at 17 yrs
*Villainess secretly poisoned Ines since she was 16
*Ines becomes terminally ill somewhere in her early 20s
*Ines forces a separation with Carcel so she can secretly die alone
*Carcel spends the year of separation fighting wars
*Villainess visits Ines when she was paralyzed in bed and could no longer speak and near death
*Villainess reveals to Ines that she poisoned her and she never intended the poison to make her terminally ill but rather make her infertile.
*Ines heart hurts when she learns she’s dying because of the villainess and her son and daughter that she gave birth to died because of the poison villainess gave her
*Ines gains strength after villainess leaves and sends for her mom to demand she avenge her and her children.
*Ines goes to a funeral to see Carcel one last time because villainess told her Carcel’s younger brother’s fiancée died
*At funeral Carcel realizes something is off with Ines even though Ines tried to disguise her dying look
*Carcrl decides her will no longer listen to Ines because she didn’t keep her promise to take care of herself
*Carcel goes to isolated castle where Ines was living to secretly die. He was very upset when he saw how she was living
*Carcel takes Ines to Calztela. Inés is unconscious for about a month so doesn’t even know how she arrived in Calztela.
*Carcel takes a demotion at his job so he could stay close to home and not be sent to war. He spends his time nursing Ines while she’s in a coma.
*He buys the small house atop Logorno Hill because he secretly read a journal note that Ines made where she wished they were commoners and lived in a little house like that with breathtaking view.
*Carcel nursing of Ines pays off. And began to grow stronger, began to walk again and before long, could walk to the garden on her own.
*Ines’s mother avenges Ines at a palace banquet by killing the villainess who was pregnant with a baby. She stabbed her repeatedly in the belly. Villainess dies
*Carcel, Ines’s father and Ines’s brother don’t know why Ines’s mother did this. The mother is imprisoned and doesn’t reveal why
*The men eventually finds out the truth just before Ines’s mother died. Her father was told the truth then her father told Carcel. That’s how Carcel found out why his son and daughter died and why his wife was dying
*Carcel’s father and Ines’s father plotted revenge against Villainess’s family to make them pay for killing Escalante children, Valeztena’s daughter, Valeztena’s mother, and Valeztena grandchildren.
*After executing the villainess family, Ines’s father step down as duke. Luciano became duke because Ines’s father was put under something like house arrest of sorts and Valeztena lost some of their standing because emperor didn’t agree with their actions.
*Crown prince causes a war when him and a drunk crown prince of another country were drinking and engaged in sexual activities with women. Crown prince shoots the other crown prince dead during drunken quarrel.
*Carcel who was injured from a war he was forced to participate in months earlier was now forced to go to war again. Inés was against it but Carcel had to go because there was risk that the other country would attack Calztela
*Before going, Carcel goes to the jewelry store in Calztela and buys Ines the diamond earrings he bought her in the current story timeline. He cries while shopping as it really sinks in that Ines is dying. He regrets that he took their third child from her. He did it to save her life because the doctors told him she would die giving birth and her health situation was risky. This is what Ines used as an excuse to separate from him five years before
*Carcel leaves for war and never returns. He died on the battlefield at age 28 or 29.
*In Calztela, Ines dies at the same moment as Carcel died on the battlefield because the priest, who is an angel or apostle, honored her prayer to die when Carcel dies.
*Since Ines and Carcel were never fated to die this way, they both got a chance to live again to correct their fate. That’s how they ended up living again.
Above is just a basic outline of T1. There is a lot of stuff missing but the above is the gist.
I think he also remembers the past
