I Became a Pornhwa NPC

Following an unexpected accident involving a truck, I woke up to a startling reality—I had become nothing more than an NPC in a pornwha. But this isn’t just a strange dream; there’s a mission I’m expected to complete. If I fail to rise as the main character, my existence will come to an end. On top of that, I’m tasked with getting involved with the heroines? Apologies, original protagonist, but it seems I’ve got no other option!
