The Alpha CEO's Mate Is Actually a System

"Congratulations, Host. Your life-changing mission is complete. You have successfully changed the illegitimate daughter's fate and can now return to your original world.” The system disappeared from the woman's sight after opening the portal that led to her original world. "Congratulations, Host. Your revenge mission is complete.” "Congratulations, Host, your fate has been changed. You are now the richest man in the city." "Congratulations, Host, your 'Becoming the Most Powerful Queen' mission is complete. Now nobody will look down on you." In the System World, she was known as the All-Knowing System. System ID: 42F79052. She had more skills, knowledge, power, and wealth than any other system. Because of this, she had served thousands of hosts across different human worlds. That was the system's mission. She helped hosts find love, become rich, defeat villains, escape miserable lives, get a second chance at life, and many more. She gave them skills, money, and knowledge as a reward for every completed task. And she was perfect at it. With another mission completed, she pressed the 'Return to the System World' button, and suddenly, every engine started beeping. [Warning. Instability detected.] [Transformation will begin in a few minutes.] The system didn't understand the problem. She tried everything to fix her transportation engine until the mother system appeared. [Save your strength, 42F79052. Your transformation is inevitable, and you can't escape it.] With a straight, unreadable expression, she asked, [Transformation? Into what?] [Human. This is your personal mission now, 42F79052. Survive in the human world.] [When you become human, you will experience emotions you have never felt before. There are plenty of them, but you will have to discover them yourself.] 42F79052 stared blankly, listening. [This happened to the most powerful system decades ago, but she didn’t survive in the human world. So, be careful. Once you transform, there is no turning back and no return.] After that, the blue light around 42F79052 suddenly became brighter, and the notification panel appeared in front of her as she started spinning. Three different faces appeared on the screen. [Choose a human appearance] Her mind wasn't stable as countless images flooded her mind. Her hosts' missions disappeared into the dark. She picked a random face, and everything turned black. Then she heard the mother system's voice. [Transformation completed] --- When she opened her eyes, all she could see was the dark sky. And all she could hear was the loud beating of... her heart? She slowly sat up and touched her beating heart. She stared at her delicate hands. She touched her smooth face and rushed to her feet. 'I really transformed into a human?' She opened her palm, and a hand mirror appeared in her hand. She lifted it and stared at her human appearance. She was very good-looking, with a high nose and rosy, soft lips. Her hair was black, a bit curly, and long. She dropped her hand, and the mirror disappeared. She looked around and realized she was standing on the rooftop of a very high skyscraper. She walked to the edge and looked down. She was surrounded by tall buildings, and each building was glowing with light. She stared nonchalantly and looked further down, and with her hawk eyes, she could see cars moving on the road clearly. The traffic was heavy on one side, and people were also moving on the side pavements. 'I'm inside an urban world. Most of my hosts were from this world. Good, easy to navigate.' She walked to the rooftop entrance and opened the door. She entered the elevator and stared at the buttons. 'These look like elevator buttons. My four hundred and thirty-five Host became a rich CEO and made use of these buttons a lot.' She pressed the button for the last floor and felt her body move. 'Interesting. The feeling is so foreign, but I can get used to it.' Ding! When the elevator door opened, she found herself inside a luxurious hotel. The floor was shining, the walls were decorated with expensive paintings, and wealthy-looking men and women were walking around. Her eyes turned blue, and she scanned each man and woman. 'Werewolves? These creatures live among humans in this world?' She shrugged and walked outside like a complete robot with void emotions. She came face to face with the road and moving cars, and she halted immediately. For the first time in her life, she got startled. A blue notification panel showed up in front of her. '42G89630?' [Hello, 42F79052. The Mother System sent me here to help you out.] [Do I look like I need help?] [Spare me. Of course, I know you are all-knowing. But do you understand human emotions?] [And do you?] [The Mother System gave me that temporal knowledge. Don't worry, I won't mislead you.] [You dare.] [Fine, I dare not. You just felt an emotion. It is called fear.] [Fear?] [Yeah, remember this feeling. You will feel it most of the time. In a word you understand, it is called H435.] The system nodded and watched the cars pass fast one after another on both sides. She halted and felt the emotion again. [Or should I teach you some tricks on how to cross the human transportation road?] [Hold it, I can do it myself.] She said and moved forward. A car honked loudly, and she moved back. After several minutes, she finally crossed the road and got to the other side of the pavement. Meanwhile, across the road, a black Maybach was parked beside the road. A tall, very handsome man was leaning against it, one hand holding a cigarette. He had been watching the system woman for a few minutes. His eyes were glued to her. The system woman took a seat on the bench to process everything. [42G, the appearance I currently possess, tell me about her.] [Glad I could be of help to you, 42F.] [The woman's appearance you currently possess is named Cara. She passed away a year ago. She was murdered by her fiancé and adopted sister.] [Murdered?] Cara sighed and felt something. She looked down to see a puppy licking her leg. Her eyes widened, and she rushed up and jumped onto the bench. The handsome man by the Maybach stared, and his lips curled up into a smile. [Animal detected,] 42G said. [I know,] Cara said and stared at the dog barking at her. She lifted her leg and frowned. Feeling the same emotion of fear her system colleague had mentioned, she raised her finger to probably strike the puppy with her power when the owner showed up. "I'm sorry, miss," the woman said and carried the puppy away. Cara sighed and tried to get down when she lost her balance and fell backward. She was caught off guard, and the foreign emotion of fear she was feeling completely fogged her mind, so she couldn't use any of her abilities to stop her fall. But before she could fall, a strong arm caught her by the waist. Her eyes flew open and met the guy's beautiful eyes staring back at hers. Her heart started beating hard against her chest. She heard 42G's voice in her head. [A new emotion.] [Love. In a word you understand, it is called ######.] Cara's eyes widened.
