How Does If I Lose You Reimagine The Canon Relationship Between 'Levi/Erwin' With Themes Of Sacrifice And Regret?

She gave him everything—her youth, her loyalty, her heart. And he repaid her with betrayal. Publicly discarded by her powerful husband, Adrian, and replaced by his mistress, Serena was left broken… carrying his child while losing the love of the son she already had. To the world, she became a forgotten woman. But years later, Serena returns. No longer weak, she is now the untouchable force behind a global empire—cold, powerful, and impossible to control. As her ex-husband’s obsession reignites and the woman who stole her life grows desperate, the truth begins to surface… especially to the child who once turned his back on her. This time, Serena isn’t here for love. She’s here for power. For truth. For revenge. And when she’s done, nothing and no one will ever be the same.

I’d been in love with Cassian Cross—my brother’s best friend, the one and only mafia boss in the NYC—for as long as I could remember. On the night of my twentieth birthday, my brother promised me a surprise. I didn’t expect that surprise to be a very drunk, very kissable Cassian. One reckless night. One baby boy. Cassian agreed to marry me after giving birth. But the day I gave birth to Leo, Cassian said nothing. He just packed up and vanished to France for nearly five years. Then he returned with Alessia. His first love. And when she saw Leo and me, she ran away and disappeared. After that, Cassian never left my side. Like he was trying to be the man I needed all along, that we were finally going to have our chance. But fairytales are lies wrapped in pretty paper. On Leo’s sixth birthday, we were driving to dinner. The brakes failed. The car spun onto the highway, flames licking at the engine. Cassian got out. And then he locked the door. “If it weren’t for you, Alessia would still be by my side. Now? It’s your turn to suffer.” It wasn’t until that moment I understood—Cassian had never loved me. When I opened my eyes again, I was back at my twenties birthday. Cassian was in my bed, exactly where I’d left him in the past. This time, I didn’t hesitate. I ran. And on my way out, I made the call I should’ve made the first time. To Alessia.

I had been in a secret relationship with Levi for five years. Just as I was about to meet his family, they went bankrupt. Levi told me that once he took everything back, he would return and marry me properly. No more hiding. No more secrecy. For him, I turned down every arranged match and waited for five years. Five years later, Levi returned as the business tycoon who swallowed my family whole. At a corporate gala, he appeared with his arm wrapped around the daughter of my family's rival. "I have to thank my fiancee," he said. "Without her, I wouldn't be where I am today." Everyone waited to see me break down and lose control. But I simply smiled and raised my glass. "Congratulations, Mr. Coleman." The next day, I called his sworn enemy. "Does your proposal still stand?" On the night before my wedding, Levi smashed open my door, his eyes bloodshot as he pinned me against the wall. "If you marry him," he said through gritted teeth, "I'll make sure he never walks away from this."

My husband, a regiment commander, once promised me he'd only accompany his depressed first love ninety-nine times. But when I finally reached that ninety-ninth tally, I saw the two of them locked in a tight embrace. After that, I stopped crying and begging him not to go to her. I only asked him for a safety locket—a small blessing for our soon-to-be-born child. At the mention of the baby, his expression softened. "When I get back," he said gently, "I'll go with you to the hospital for the checkup." I nodded obediently. I didn't tell him that ten days earlier, I had already filed for divorce. Now, our divorce was final.

During a thunderstorm on the border, my fiancee, Eleanor Ashby, covers my retreat and falls down a cliff. The search and rescue team spends three months searching through flash floods without finding a trace of her. Everyone concludes she's dead. I refuse to give up and spend another two years looking for her. Eventually, I find her at a small clinic in a remote mountain village. But she's become the wife of the clinic's caregiver, Dylan Foster. That's when I learn she's lost her memory and fallen in love with someone else. In my previous life, I ignore her wishes and force a renowned neurosurgeon to use a high-risk treatment to restore her memories. The day her memories return, the man who has cared for and protected her for the past two years throws himself into the river in despair. Later, during an earthquake rescue mission, Eleanor and I are trapped beneath a collapsed mountainside. There's only one narrow escape route wide enough for one person. She forcibly pushes me out. Moments later, a second collapse buries her beneath a massive boulder. With her dying breath, she reaches through a crack in the rocks and grips my hand. She says in a hoarse voice, "Callum Pierce, these ten years we've spent together is repayment for the debt I owed you from the ten years before. We're even now. Neither of us owes the other anything anymore. "If there's a next life, don't let me remember the past. Please... let me be with him." Tears blur my vision. When I open my eyes again, I'm back on the day I find Eleanor. This time, I choose to respect her decision and let go of the life she's forgotten.

Lila Carrington gets the most shocking news from her father at dinner one day, and all he said was a decree that she has to follow through with even though she has her own reservations—she was supposed to tie the knot with Levi Beaumont. The Carrington and Beaumont families have been enemies for decades, and truthfully none of them know the real reason behind the fight because each person seems to have their own side to the story, so Lila did not understand the reason that her father, who taught her never to associate herself with the Beaumont family, was the same one pushing her into marriage with one of them. Levi did not want the relationship either, but the families had to form an alliance so they could both remain in business. It had to be done. Driven with the passion to stay in business, Lila and Levi help their family out, but with the promise to their parents that it would only last a year and they would be done. What happens when they begin to fall for each other? Do the Carringtons and the Beaumonts reunite, or does a war happen? Legacy of Love and War is a romance like you have never seen before.
