Does it get better and when does the satisfying downfall of lize start??
Spoiler :
On side story. In main story lize will still triumph. Her simp man still loves her so much, he actually knew lize tried to kill MC few times but he just kept silent. Don't bother with in laws. The parents barely ask for forgiveness.
Lize will still get married because of her simp ass husband.
But later in side story, or MC & ML are leading happy life, having kid, prosper territory and more. ML knows how his family treated MC, so ML deliberately never visit his parents, only letters.
The in-laws asked mc & ml to visit them after their kid around 4yo. While they are on the way, they found a boy (he is nephew of the king, I might be mistaken, it's been so long since I read the novel, but the boy is royal). MC hired the boy to be her worker because the boy is super smart. When they arrived at duke manor, turned out Lize has faked the royal boy, just so she could have reward from the king. So she can still winning against MC. But someone from royal family, the boy's mom, didn't recognize the kid lize brought but instead recognized the kid MC & ML brought. The boy finally confessed he was the lost boy, he was lost because when he was younger, his aunt told him his mama hated him so he ran away from home. He is smart because he already received education, he can read and polite.
You see, in side story, while mc & ml living happily life. Lize & the duke family are miserable. Lize constantly wanted to "win" against MC, because MC & ML achievements are famous in the dukedom. Lize throw a lot of expensive luxury party, even tho in laws against it. She doesn't wanna sleep with her simp, so they can't have child. Finally the simp realize Lize is truly horrible but he can't divorce her because the prenup. Back to the present, king angry with Lize faking the "royal nephew" and sentenced her to prison or something. But because she is future Dutchess, the king annulled simp & lize. Finally lize in jail. While the stupid simp asking forgiveness from his brother and MC, and he said he doesn't wanna inherit the dukedom anymore because he is stupid. But ML told him no. He likes his own territory and it's your own responsibility, so own it. Few years later, the guy married someone else, someone far from lize.
