I Longed for Peace and Was Forced to Become the King of Popularity

I am Bai Hualan, just an ordinary high school student. My biggest dream is to get admitted to a university in a safe area and get an allocated house. On this day, I awakened to a super popular king system. As long as you follow its so-called plot and perform well, you can get various rewards. But it is still too dangerous. Anyway, there is a protagonist to save the world. People like me just need to stay in the safe zone, right? What does it mean that the protagonist dies and I want to take over?
