Rebirth: No Longer My Brother's Double

In my past life, Noah Luther, my brother, runs away from his engagement. The bride, Julia Zimmerman, shows no resentment and simply switches the arrangement to me right on the spot. She is courteous and thoughtful toward me after the wedding, but that all changes when Noah crosses someone abroad and has his limbs crushed. She actually spends the whole night in the study after learning of that incident. I assume Julia is worried about my safety when she sends over a dozen bodyguards to me the following day, a gesture that touches me deeply. I suddenly lose consciousness out of nowhere the next day. Then, I get abducted to an abandoned factory and have my hands and legs crushed bit by bit. It's so painful that I try to bite my tongue to commit suicide from the agonizing pain. Julia walks in slowly, looks at my condition, and says wistfully, "So that's how much pain he went through back then." When Noah trips and falls during rehabilitation and loses a tooth, Julia violently pulls out my tooth with pliers that very same night. She looks at my bloody mouth and says calmly that she's only doing this for my sake since I eat too much. Soon after, I "happen" to fall down the stairs when Noah sprains his back, forcing me to stay in bed for three months. Julia even breaks a cup and drives the shards into my hand when Noah accidentally slices his finger while chopping vegetables. Noah later dies in a car accident abroad. Julia drags me to a bridge over the river and jumps off with me, saying, "You're just a stand-in for him. He's dead now, so you shouldn't live either." I open my eyes and find myself back on the day Julia arrives to talk about the wedding arrangement. Noah has already fled through the back door, so she looks at me coldly and says, "I'll marry you, then." I merely smile and say, "I'm already in love with someone else, so please find another person for this marriage, Ms. Zimmerman."
