I Became a System in Another World, Hostesses, Stop Chasing Me

From the Start, I Got Hit by a Car and Became a Vegetable? The Heavenly Dao saved my life and sent Liu Xiujun to another world to complete a mission. He pretended to be a System and helped the heroine rise to greatness, but she actually followed me back to the real world. Help! I really was only completing a mission… I lay low until the heroine was in danger, then showed up pretending to be a System and assigning her tasks. Did I end up raising her into an empress? When I returned to the real world to carry out a mission, I ran into my best friend, who had been reincarnated as the empress. Wait, big sis, what are you doing here? At long last, I made it back to the real world, but the empress wasn't having it. She insisted on chasing Liu Xiujun down and making him take responsibility, or else she'd kill him? You followed me back to the real world, and now you're with my best friend? The little girl grinned slyly.
