Broken! I've Become a Miserly Male Lead

When Su Cheng woke up, he found that he had become the second male lead who poured out his heart and soul for the heroine without asking for anything in return. He originally wanted to change the status quo, but the system insisted that he help the heroine dominate the world, otherwise he would have to be wiped out. He refused at first, but unfortunately the system gave him too much. Moreover, Su Cheng gradually realized that he didn't seem to have to revolve around the heroine.
