A gentle protector who sees the girl she hides. And a dangerous man who thrives in chaos.

The first thing I do after being reborn is dump my devoted boyfriend and immediately say yes to the obsessive man's pursuit. In my past life, my so-called best friend, Sarah Cole, bound herself to an app that could transfer all of my boyfriend's love for me to her. My boyfriend was Luke Spencer. The golden roses he prepared for me ended up with her. The hotel he bought for me suddenly had her name on the deed. The way he looked at me shifted from fierce desire to cold disdain, but when he turned to her, his eyes overflowed with the tenderness I once knew so well. When I cried and demanded to know why Luke had changed, he just looked at me with disgust as he spat, "We broke up a long time ago. Leave my girlfriend alone!" On my birthday, Sarah went live online, flaunting how Luke had rented out the entire amusement park for her. Fireworks lit up the sky behind her in a blaze of color. And me? They worked together to have me thrown into a mental hospital. They called me a crazy woman obsessed with someone who never loved me back, and in endless rounds of electroshock therapy and forced medication, I died in despair. When I open my eyes again, I'm reborn. This time, I no longer feel anything real for my ex-boyfriend. Instead, I play along with Ethan Grant. I find it funny when Sarah opens the app again, siphoning away every drop of Ethan's overwhelming love. I really want to know if she can handle it.

My father, Daniel Jacobson, teams up with the elders in my family to launch the Family app. Every child's behavior is converted into points, and those points determine who inherits the family's wealth. As the least favored daughter in the family, I am one of the first people forced to use it. "You earn one point for greeting your parents. Massaging shoulders or washing feet gives you ten points. Handing over your entire paycheck gets you 1,000 points. This is my original digital system for measuring good behavior." If I dare complain even once, or if I rank last on the scoreboard, Dad humiliates me relentlessly in the family group chat. He even forces me to kneel and wash the feet of whoever has the highest score as an apology. He looks at my hands that are red and scalded from the hot water and sighs. Then, his expression turns resolute again as he says, "I know it hurts now, but this is for your own good. A rough diamond has to be cut and polished before it can sparkle. I'm helping to smooth away your rough edges so your future will be smoother. "The points system is my greatest achievement. It's the deepest expression of a father's love." Today is Independence Day. It's also our family's annual scoreboard finalizing day. Dad invites all our relatives over. In front of everyone, he plans to announce that I, the child who ranks last, will be disowned. He wants everyone to see what happens to anyone who dares challenge his authority. "I'm doing this for the good of our family. Without rules, there can be no order. And without a strict upbringing, you won't build up the perfect character. One day, you'll understand my good intentions." But, Dad... I have already ended my own life by overdosing on some medicine. Right now, my lifeless body lies cold in the room upstairs, waiting for you to uncover it with your own hands.

After I got a second shot at life, the very first thing I did was enroll in an intensive weight-loss boot camp. In my past life, my boyfriend was always on my case about my weight. He flat-out told me he wouldn't put a ring on it unless I got down to a hundred pounds. I tried every diet and workout plan out there—I pushed myself to the edge—but instead of losing, I packed on even more pounds. Meanwhile, my so-called best friend ate cheeseburgers, fries, and pizza like it was her job and still dropped from 130 pounds to a hundred in less than a month. The second she hit that magic number, my boyfriend's head turned. They started sneaking around behind my back. When I finally confronted them, they shoved me off a rooftop. It wasn't until after I died that I discovered the truth: my "best friend" had linked herself to a weight-transfer system. Every single pound I struggled to lose went straight to her. And every ounce of fat she should have gained? It landed right back on me. When I opened my eyes again, I was back on the exact day my boyfriend gave me his hundred-pound ultimatum. With every memory of my past life intact, I couldn't help but smile. My best friend wants to be skinny, does she? Well then, let's see how she likes being nothing but skin and bones. Let's see if forty-five pounds is skinny enough for her.
