We have a horrifically abused MC who has been forced to live a lie and had every dream crushed.

She desperately hoped she'd be able to escape her abusive birth family and have a better life once she got married, and genuinely tried her best to be a good wife and get her husband to love her. It was all in vain and her hopes were ripped to shreds like wet kleenex.

The ML never gave her a chance, let her be publicly humiliated and painted as a bad person, and basically ignored her until she went insane starving for affection and attention. The entire marriage, her family continued to be physically and mentally abusive towards her, so she couldn't even escape that.

Then her husband unilaterally decided to adopt a child and not tell her, with the kid's mom publicly grinding it in her face as the first she hears about it. Which was her final straw.

She set up a tea party, and invited him. Wherein she, with extreme bluntness, told him she was being abused and called him out on his hypocritical a**holery. She (rightly) points out that he is just like every other as*hole man, viewing her as an accessory of another man, her father, and never as her own person. He never tried, and judged her falsely. She wonders how he could have missed all the abuse.

He, massive derp that he is, tells her he noticed her many, many, CONSTANT injuries, and constellations of scars, and reveals he didn't care enough to wonder how she got them, or be concerned she was always hurt. He then makes some bullsh*t lipservice that if she had told him, (which she had. Couple of times. So I guess he means if she'd told him better) of course he would have helped her (so it's allllllll her fault).

He then drops dead from poison while his indifferent wife watches.

I was like "YESSSSS!!! I am HERE for this!!!!"

The first chapter contains angst ML treat the FL coldly before and after they got married. he dont really care about her its because the FL is a daughter of his enemy (fl's father) so for the chapter 1 FL poisoned the ML she also say that their marriage is terrible but the ML thought he is going to die since he cough some blood the FL didn't call for a doctor nor call anyone to help her husband which is our ML she coldy turned around. When the FL woke up she regressed back in time before they got married

The ML is now laying on the ground he is overthinking why his wife poisoned him 'did she hate me enough to poison me?' is our marriage that terrible?'he began overthinking actually the FL ask for a audience/tea time (back then before the poison happen) ML of course accept it because he is planning to clear up some misunderstanding by communicating to her.... So here is the reason:the ML turn back the time using a glass (?) thing like that, that thing can also turn back the time but he didn't know what year he will go back but he just hold it with his hand wishing to turn back the time before they got married (there some important thing mentioned in the chapter I forgot it) so when he succesfully turn back the time he still remember he's past life and how he die by the hand of his wife (fl)... TIME SKIP:ML approach the FL and start being kind to her (FL also remember her past life) which lead to our summary

"I admit that my words and actions were worthy of misunderstanding, but I don't love you. It can never be. You are 'the enemy who poisoned me'."yes this is what I mean of course at the end of the summary it looks like the FL is planning to run away so im looking forward to that scene

In the present reality, I did not kill him'this is also part of the summary so the FL didn't really kill him after they regress. FL also got abuse by her own family all part of her family are tr*sh they only use her to replace their dead daughter
