Chapter 1 is supposed to set up why this life charge scenario is necessary to the MC. What exactly killed him? Is the FeMC responsible for his predicament? Do Ghosts and Zombies actually exist in this setting, if MC bothered to dump exposition about them? Chapter 1 doesn't answer these necessary questions, so I have no immediate reason to continue reading.
The fact that I don't even learn the main pair's names (Felix and Lulu) until Chapter 2 is a worrying sign.
