The Villainess's Wise Retirement Plan MTL

I was reincarnated into a game, but it was my younger sister who died while tormenting my older sister. What did a worn-out female protagonist say to my beautiful older sister? I tried to escape the original story by taking care of my older sister... "Take this. Lillian. It's your doll." My father threw the original male protagonist at my feet. It seemed like a mess from the start, but somehow he managed to interfere with the male protagonist♡female protagonist love line! "Are you trying to get your eye on Lillian's again?! She's mine, and I'm going to play with her!" In order to prevent the two from meeting, she showed off her obsessive princess side without holding back, while struggling to survive in the ruined world with her weak body... "The scrap metal, no, the machine you made is a revolution!" It seems like she surprised the world with her engineering. On top of that, maybe it's because she stirred up too much around her to get capital and materials? The people around her started to get strange. "Why did you hide it? Your symptoms!" "I'll chase down anyone who messed with you to the ends of the continent and kill them." Aren't those shameless brothers nagging, "I've collected all the herbs in the North. Live, Lillian." It seems like even the strongest father in the North has turned around. And... "You want to run away? Then try running again. I'll keep telling you. No matter how hard Lily tries, there's no way you can leave my side." ... Why are you saying those lines to me, you crazy male protagonist. In the original, he just wanted to retire gracefully and live a comfortable life with rabbit-like machines. Will he succeed?
