Chat Group, Please Stop Using Me

Yi Zheng transmigrated, and his System was [Reversal]. Important memories were blurry, while trivial details stuck in his mind; deadly poison became a tonic, and curses turned into buffs. He was practically no longer human! One day, he was chosen by a chat group. Under the System's influence, even the effect of the "Endless Lock" he drew changed: he would willingly let others control him, and after each "use," the user had to give him a reward drawn from his heart. So, to become human again, Yi Zheng decided to make a deal! London Deserter: "A born strongman, and the loneliness that comes with it. Without a doubt, I will be the one to teach you about love!" Child of Prophecy: "Master, I want to take you to see the stars that don't exist. Perhaps you'll find some of your lost past there." Kaname Madoka: "If I can turn you back into a human, my reward will be the happiness of being able to 'save you.'" Machine Calamity: "My reward is to complete the synchronized calculations for 'understanding' the heart." The gifted Furongwang cigarette: "Wait, wasn't I here first?"... He thought this was a sure path back to his humanity. Who knew his fellow group members would really treat him like a "power bank" and try to claim him as their own? "Don't get the wrong idea. We're just making a simple deal." The girls: "I'm really going to have to keep you under control!"
