I don’t get why he hated her in the original novel, only to magically fall in love with her later. Is it just because she opened the cage? But how the hell did some random guys even manage to lock that fking LION in a cage in the first place? None of this makes any damn sense!! LMAO.
“She can die for all I care. Just get me the body.” *She opens the cage* “OMG, YAMETE~ DON’T SAY MY NAME LIKE THAT, I’M GONNA BLUSH UWU

I took this from noveluptades.
"
In a past life, the male lead (Aslan) and the female lead (Vivian, then Eleonora) were lovers.
She gave birth to his child, but then died, having sacrificed herself to seal the demon.
Someone later showed Aslan the child, and he assumed that she had loved another man and had a baby with that man.
Aslan was crushed, thinking she had betrayed him. And of course, took another empress and EVEN HAVE ANOTHER CHILD WITH HER!
Out of grief and love, he still raised the child, but never acknowledged him as his legitimate heir.
Why? Because he wanted Eleonora (Vivian) to be remembered as a hero who saved the world, not just as the emperor’s first woman.
After realizing the truth at the end of that past life, the male lead was filled with regret and longing.
So he began to reincarnate over and over again, just to meet her again — to have a chance to do things right.

Oh poor him, loved FL to his death in their first life, surrounded by his new wife, child and riches. Now he wants to keep him and FL reincarnating together just to have FL love. FUCK OFF.
And there were spoilers saying he slept with the half sister in their second life and was obsessed with her, and kills FL because of her (original novel).
I can't believe an author would ever write a ML with this kind of behavior. I gave up reading this, disgusting.
