Does 'My Sister Is My Ex' Have A Manga Adaptation?

In order to become the sole heiress of the Xander family, my younger sister schemed and manipulated, pushing me into depression and driving me to attempt suicide.Upon my rebirth, I vowed to seek revenge and would not tolerate injustice.It wasn't until one day when I met a girl who looked exactly like me that I discovered the truth: my sister was a fake heiress, and she harbored many hidden secrets...

I failed my college entrance examination. My father decided to sell me to the village chief’s hot-tempered, crippled son. My younger twin sister helped me escape in the middle of the night. It was only later that I discovered my younger sister was the one who had failed the examination. She used my identity to attend college and hooked up with a rich heir. At her engagement banquet, they revealed the truth that she had taken my identity. As a result, the event fell apart. Out of rage, my sister pushed me down the stairs. I grabbed her and pulled her down with me. When I opened my eyes again, I returned to the day the examination results came out.

I return to the country after attending an international anesthesia academic conference. That's when I see the news of my boyfriend and twin sister getting married. I'm anxious to verify its authenticity, but my sister drugs me and induces me. "A substitute's child will only be an unwelcome bastard even if it's born. I'm just helping it move on to a better life." Then, she slices me open with a scalpel. She gouges my womb out, causing me to die from significant blood loss. Meanwhile, my boyfriend believes her lies. He's sure he's not the father of my child. He ignores my messages begging him to save me. Instead, he spreads the word about me eloping with someone else. He even wipes all traces of me from his life. "I will never see her again, forever and ever." Five years later, surveillance footage of my sister cruelly murdering me surfaces.

My mother gained access to an exchange system the year I turned eighteen. She swapped my college entrance exam scores with my sister, Poppy's. She swapped my high-paying job for Poppy's, too. She even wanted to swap my perfect boyfriend and hand him over to Poppy. However, she had no idea that I had deliberately found him at a wife-killer club. When my boyfriend suddenly fell for Poppy and fell out of love with me, I smiled. I had been waiting for this day for a long time.

Having a crush on someone and getting married to him is supposed to be the best thing ever happened to you. But what if he happens to love your sister and destiny chooses you as his bride. His replaced bride_

When I get married to Zachary Lennor, I know that he has a younger, depressed sister who's a huge pain in the ass. On our wedding night, she suddenly barges into our room with the excuse that she's terrified of the dark. That's why she wants Zachary to sleep with her. When I get hospitalized due to my illness and need Zachary to take care of me, his sister insists that he go home to eat all three meals with her every day. Otherwise, she'll go on a hunger strike. Even when Zachary and I are on a date, his sister will call him immediately, claiming that her depression is acting up. If he doesn't go home right away, she will jump off a building without hesitation. Unable to take it anymore, I unleash my anger on Zachary's sister. But Zachary is quick to shield her from my ire. With an icy expression, he tells me, "I only have one sister, whereas I can always get myself another wife. If you can't stomach her presence at all, we'll get a divorce right now." I keep tossing and turning in bed at night, unable to sleep at all. That's when I decide to get out of bed just so I can apologize to Zachary and his sister. As soon as I walk to the doorway, I hear a familiar voice whining from the master suite, where Zachary stays. "Zach, since Samantha got so mad at me today, does this mean she's found out that I'm not your actual sister at all, but your ex-wife?" Zachary pauses momentarily before saying reassuringly, "Even if she does, it's fine. Although I do love her, I've already vowed to stay with you forever the day I married you. "So, even though we're already divorced, I will still keep my word. I won't let you go." At that moment, I finally realize that Zachary's so-called younger sister is just a fake identity. Her depression is also a big fat lie. I'm the only one who's been kept in the dark about everything in this performance. In that case, I'm not going to humor these jerks anymore.
