Can You Explain The Ending Of The Great Mental Models?

The doctor told me I had 72 hours left, unless I got access to the newest experimental treatment. However, there was only one slot available, and my husband Bowen Liddell gave it to my sister Yvonne Lawson instead. "Her kidney failure is more critical," he said. I nodded and swallowed the white pills that would only speed up my death. In the time I had left, I got a lot done. The lawyer's hand trembled as he passed me the documents. "Are you sure you want to transfer the two billion dollars in shares?" I replied, "Yes. Give them to Yvonne." My daughter, Candice Liddell, was giggling in Yvonne's arms. "Mommy Yvonne bought me a new dress!" I said, "It looks beautiful. Make sure you always listen to Mommy Yvonne, okay?" The art gallery I built from the ground up now had Yvonne's name on the sign. "You're too kind, Kathy," she said, crying. I told her, "You'll run it even better than I ever did." I even signed all my parents' trust fund away. That was when Bowen finally gave me his first genuine smile in years. "Kathleen, you've changed. You're not so aggressive anymore... You're beautiful like this." Indeed. This dying version of me finally became the 'perfect Kathleen Sullivan' in their eyes—obedient, generous, and no longer argumentative. The 72-hour countdown had already begun, and I couldn't help but wonder what they would remember when my heart stopped for good. The good wife who 'finally learned to let go', or the woman who completed her revenge by dying?

My husband is poor. We've already been married for three years, but I've covered all our expenses during that time. Even when I'm interested in a cheap bag when we go shopping, he says it's too expensive. He tells me not to buy it. Later, I discover that he gives his first love a four-million-dollar diamond necklace for her birthday. It turns out he's not broke and heavily in debt—he's the heir to an affluent family with a net worth of billions of dollars.

My father, Cameron Howard, and I are transported to an ancient world together. The system tells us that if we can each win over a target, we'll be able to return home. My mission is to win the heart of a ruthless princess, and Dad's mission is to conquer a hot-tempered queen. The princess breaks two of my ribs and ties me behind a horse that drags me for miles. The queen decides Dad isn't kneeling straight enough. So, she crushes his knees with iron tongs and forces burning charcoal into his mouth until he loses his voice. For three years, we live miserably. Just as the system announces "Mission failed", the princess standing before me suddenly smiles. She tears off the mask covering her face. The person underneath the mask is my wife, Abigail Finch. She walks over to the throne and pats the fierce queen on the shoulder. "Mom, haven't you had enough? Cameron and Oscar are almost dead from everything you've put them through." The queen removes her disguise and looks up. It's my mother, Elisha Sweeney. She claps her hands toward the officials filling the throne room. "Alright, everyone. You can get up now. That's a wrap." Dad and I exchange stunned looks. Mom gently squeezes my crippled hand and sighs. "Does it hurt, Oscar? You and your dad made Kenneth Ingram's life miserable every day. You even drove his son, Joel Ingram, into bankruptcy. You've suffered enough now. Consider the score settled." The officials throughout the court remove their wigs, revealing walkie-talkies and sweat-soaked T-shirts beneath their costumes. But none of them know that the transmigration is fake, but the system is real. In the final moments of our lives, Dad and I make a pact with the system. We offer up both of our souls as the sacrifice in exchange for a lifetime of wealth, peace, and happiness for them.

I have the ability to see how people will die. The day my divorce is finalized, I'm hit by an electric scooter and sent flying. When I wake up, I see a line of text above the nurse's head. It reads, "27 years old. Breast cancer in eight years." I pick up my phone. The first name in my contacts is my ex-wife, Caroline Meyer. After a moment's hesitation, I open her social media. Her latest post shows her and her new boyfriend vacationing in Marencia, captioned, "Forever starts with you." The location tag says it was posted three hours ago. We only finalized our divorce the day before. Later, I get a voice message from my daughter. "Daddy, Mommy says I can't go to her new house anymore. Her boyfriend doesn't like kids." I clutch my phone and head out to pick her up, only to run into Caroline's father, John Meyer, outside the apartment building. Above his head, the words read, "62 years old. Carbon monoxide poisoning in three months." The moment John sees me, he starts yelling. "What a loser! My daughter should've divorced you years ago! Her new boyfriend is young, handsome, and owns three houses. What do you have?" I glance at the words above his head, then slowly delete the warning text message I'd already typed out. After that, I take my daughter's hand and say, "Come on. I'm taking you out for burgers."

When he and his father eventually decide to begin a new life after his mom and sister's death, Praxis Cohen, a suicidal teenager with an expressionless visage on his face, finds himself in a huge, formidable laboratory where teenagers like him are being injected a drug of which the effect is still unknown. Fortunate enough, his body can withstand the drug that leads him to be declared by Dr. Conscire as the first patient to have successfully passed the First Stage of the experiment in this generation. As he proceeds to the Second Stage, Dr. Conscire, the president of the organization, decides to release him off the laboratory to find out that the effect of the drug enables him to read minds and do psychokinesis that sets his mind into chaos. In his debacle as an experimented guinea pig of the nameless organization, realizing that he is not alone in this experiment, Praxis meets new marvelous people to discover the origin of the experiment, the reason why they turned into supernormal beings, the connection of this experiment to the unborn world war in the future, the twists and turns of their past stories, and to discern the next stages of the experiment. With the collaborative effort of their team, they strive to choose the best course of action to put an end to this fight.

The 100th time Dexter Carrington ditches me to help my best friend with her lab work, I write the final line in my diary and break up with him. Dexter is exasperated, to say the least. "I genuinely don't know how your amygdala is wired. Your emotions have completely bulldozed your rational thinking." My best friend, Brianna Holt, laughs. "That's cruel. You're insulting her intelligence in words she can't even understand." She's right. I don't understand. The two of them dominate the biology department rankings every year, taking first and second place, and are the kind of prodigies even their professors defer to. I'm just an ordinary student at the music school next door. When they talk about how cells have their own rhythms, the only thing I can think to ask is what time signature those rhythms are in. Dexter always hates that. "If you don't understand, don't chime in." So now I listen. I don't chime in anymore. Because the first page of this diary reads, "Today is my birthday, but Dexter chose to go over data with Brianna. "By the time this diary is full, I'm leaving him for good."
