I Killed the Main Player

Synopsis

Being a character of your favorite game is great! Sure, he's just a minor NPC, but Corin knows this game like the back of his hand. With his knowledge and the main player Sihu's abilities, everything's going smoothly—until Corin discovers Sihu's been murdering innocent NPCs and stealing their items. Horrified but powerless to stop him, Corin awaits the end of the game—only for Sihu to mysteriously fail at the last mission. Instantly, Corin travels three years back in time. Now, he's determined to kill Sihu and take on his role—defeat the final boss and save the world. (Source: Webtoon Entertainment)
