Is 'For The Sake Of' A Common Phrase In Manga?

I struggle with all my might, but Dad restrains me, and Mom breaks my limbs. Then, my sister seals me into the concrete. "Concrete is only brought to life with an actual person sealed inside. It looks so much more defined! It's not like you'll die after being sealed in there for a few days. How can you be so insensible?" The pain of having my limbs broken and my oxygen being cut off leads to me dying within that block of concrete. My body rots and festers inside, but my soul sticks around to watch how my parents dote on their adoptive child. They seem to be happy without me. Finally, I lose all hope in them. But when the liquid from my body seeps out of the concrete, they all lose their minds.

My husband searches for doctors everywhere to cure me of my stomach cancer. I think he loves me to the core, but after I recover, he takes away my left kidney to save his true love, who's been comatose for two years. He leans down to kiss her as I watch. "She owes you this; I've finally made her repay you. You'll definitely get better after this." What he doesn't know is that I'm already weak from the cancer. I die after he takes my kidney. That's when he goes crazy. He breaks down in tears and screams at the doctors. "Didn't you say she wouldn't die?"

In a drought-ravaged apocalypse, I kept our entire apartment block alive with my “watermaker” ability. But when I grew weak, my neighbors shattered my limbs and turned me into a living water source. Later, when raiders stormed in, they dragged me out to take the blade for them, only to realize that even my severed arms could still produce water. So, they shouted about “saving humanity,” then shoved me into the crowd and fled in the chaos. People rushed forward one after another, tearing at my flesh. But I didn’t die. What was left of me fell into the hands of a monster, and I was subjected to inhuman torment day after day. Ten years later, when the apocalypse finally ended, that monster tossed me into an incinerator. Only then did I die. When I opened my eyes again, I had returned to the moment I first awakened my ability, just as my neighbor knocked on the door, begging for water.

When the half-mile sprint test is about to begin, Quiana Sullivan, the class president, and I have applied to be exempted from it. My own mother, who's the homeroom teacher of my class, approves Quiana's application with a smile. But she then throws mine to the floor. "You're having a chest pain, you say? I can't believe you're able to come up with such lies just to avoid the half-mile sprint! I'd have known if you had a heart condition! "Quiana is weak by nature, not to mention she's on her period right now, so she can't handle the agony. What about you, hmm? You've always been perfectly healthy, yet now you're telling me that you're suffering from heart pain? "Don't go around embarrassing me just because you want to slack off! I don't want others claiming that I'm being biased toward my own child! As long as you're still alive and kicking, you must finish the half-mile course no matter what!" Left without a choice, I can only return to the field. The cold wind makes me feel even dizzier now. My heart keeps contracting uncontrollably against my will. Suddenly, it just stops pumping. The next thing I know, I collapse onto the grassy field heavily. When my consciousness is about to flicker to darkness, my mom finally walks over to me. But she merely kicks my arm with a frown on her face, and her tone remains glacial. "Stop playing dead. Get up right now." She doesn't realize that I can never open my eyes ever again. Isn't this great, Mom? No one will ever claim that you're biased toward your own child. I've used my life to prove how fair and just you are. You must be happy now, right?

"Who said I hated you?" It took me a moment before I could process what this man just said. "What do you mean you don't? Na-" He grabbed my hand suddenly and looked me in the eyes which caught me off guard. "You keep saying her name that it annoys me to the point that I just want to erase her existence." Is this man seriously telling me that he'll kill the female lead?

After I get reborn, I've orchestrated every missed moment with my biological parents. When they want to take my adopted sister, Simone Graham, to take a family portrait, I'll take cold showers so that I can catch a fever. When they decide to book a cruise ship overseas in order to celebrate Simone's birthday, I join a classified project, which stops me from leaving the country. When they start a company for Simone, I quickly apply to get dispatched to South City, which is 600 miles away from my hometown. I also make sure to declare that I will never fight with Simone over anything in life. In my previous lifetime, Simone and I had been fighting over our parents' affection for decades. But all I got were comments on how manipulative and cunning I was. Everyone preferred Simone, who was pure and innocent, while showing disdain toward me, who was a woman of little words. Even my own husband and child couldn't understand my pain at all. "We're all family here, aren't we? Can't you just stop your dramatics for a few days? Whenever I come home, you always start a fight and cause unrest among everyone! You really should reflect on your own actions!" Just like that, I died on my sickbed all alone. When I open my eyes again, I've returned to the day I get accepted back into my family. This time, I'm not going to fight anymore. I'm going to live for myself instead.
