Talk with System - 2

[I know what you're thinking, so let me explain how it was all your fault that you died.]

[Because you broke the rule 101 of living in any world, you messed with the protagonist.] The system spoke and before Rio could ask anything else, it confirmed his doubts-

[Yes, Kevin was the protagonist. Your role on earth was just a nobody in the train scene. But instead of acting like how a normal man should act and get angry over it, which could lead to a fight where protagonist needed to show off his capabilities, you kept silent.]

[After ruining his one plot, when heavens tried to fix it by adding another fight scene, you somehow jumped into the scene of that kidnapping and ruined his plot to save the school beauty too.]

[If that wasn't enough you also went nuts and picked a fight with him for no reason. So as a punishment heavens decided to alter the plot's direction and it led to your untimely death.]
