Here are some Spoilers i have found (not from me I just copied it):
Trigger Warning though, there are very detailed description of
r*pe by Non Male Lead, r*pe by Male Lead, and su*cide in this story
Also this is by the same author as Omega Complex and Alpha Trauma, to give an idea of the author's writing style.
The basic plot:
Jung Seijin and Kwon Yido were in an arranged marriage where everything that could go wrong, did go wrong horribly. It ended up in a tragedy.
But that was their first life and the story started at the beginning of their marriage in their second life.
Not that Jung Seijin remember, but Kwon Yido certainly did and was doing his best to fix everything that went wrong with their first life (which he mostly caused by being a flaming piece of shit).
Now onto the characters:
Jung Seijin:
Our main character was the adopted dominant omega son of a middle-ish conglomerate family. He was adopted to be used and that family really did squeeze every drop of worth they could from him. His main use was, of course, to be married off, but since he was a capable manager, so he was also in charge of their company until his marriage.
Well one could expect, they didn't treat him good and so he was in desperate need of affection and care. His personality was obedient, with a calm but curious outlook. He wasn't exactly naive, but he had been restricted all his life and be forced to become a doormat, so he wasn't too good at expressing his sides, needs, and wants.
Kwon Yido:
This man was a textbook case of scum Alpha buying an Omega in their first life. He was made to be hated and if Seijin wasn't in such a bad place mentally after years of abuse by his 'family', it was doubtful he would have stayed with that version of Kwon Yido at all. No self respecting person would.
As always, his regret came far too late. If it wasn't for the regression, there wouldn't be any story.
In the second life, he really did try his best to make things right for Seijin. He was a gentle and caring man who arranged everything for Seijin's best and pushed Seijin to aim for his own happiness and independence. Away from him, because he felt (rightly so) that he didn't deserve Seijin.
He really got his crematorium set at the easiest level. All the bad things that happened were things that he could have easily handled if only he paid a little attention, so now that he even knew the future, they were quickly dealt with. Seijin didn't remember anything and was in desperate need of affection, so he easily gained Seijin's love and affection again, so much that Seijin couldn't stay away even after remembering their first life.

They both regressed. Kwon Yido is an absolute trash in their first life and caused Seijin to commit suicide in despair. That's why he tries so hard with this second chance, but he is ready to let Seijin go if that was what Seijin wanted. Their relationship only progressed once Seijin remembers their first life and took a timeskip to forgive Kwon Yido.
No one died… read the raws…
