The Male Lead Keeps Interrupting My Faked-Death Progress Bar

Comments by chapter are open, with restrictions. [Story blurb, told in first person; the main story is in third person]: I'm an NPC extra. The System tells me my mission is simple: 1. Become friends with the male lead. 2. Take a hit for him in a moment of crisis. 3. Die in his arms, delivering my scripted final words tragically, so he can power up in grief and fury and defeat an enemy above his level. The System says my death will create a tearjerker moment, and then I can retire. I nod to show I understand everything. * Then I discover that the hardest part of this mission isn't “becoming friends with the male lead.” It's “dying.” ...Can someone explain why the male lead powers up faster than I can say my “final words”?! I haven't even fallen down, and the world-shaking BOSS has already been beaten to death by the male lead going berserk! All I can do is lie low and wait for another chance to sacrifice myself, but... Aaaah, how did it turn out like this? The male lead powers up way faster than I can lie flat. I really can't find an opportunity! “I won't let anyone have the chance to hurt you... Never.” ...Thanks, but you really don't have to go that far for a “friend”! Why does the male lead look even more upset after I say that? System: “How about you check the tags?” I look, and there it is: a perfectly good “hot-blooded youth” story, with “plenty of romance” added afterward. Me: ??? What does that mean? I don't get it. Come to think of it, the latest “Most Popular Character” poll was won by someone with the same name as me... Wait, that's me! Huh? I'm really just an extra! A cool, reserved airhead girl x a sunny, sweet-on-the-outside, dark-on-the-inside boy [Reader's guide]: 1. An urban fantasy setting with monsters and supernatural powers. She transmigrates into a manga. There will be some forum posts, but they aren't the focus. 2. The System gets quite a lot of screen time. It's basically the comic relief, always ready with a quip. 3. Not quick transmigration. Not quick transmigration. She transmigrates into a book, not through multiple worlds. 4. All place names are fictional cities. Fuhai City and Qionghai City, which is mentioned in the manga, are both fictional. Please don't associate them with real places. 5. I'll let the old comments stand. Burying them means dealing with them one by one, and after trying a few, I realized it's a huge hassle. I give up... If any strange comments show up later, I'll bury them when I see them so readers who enjoy this book can have a pleasant reading experience. If you need to find them, look in the buried-comments section. If someone says something truly outrageous, I may delete the comment. Theme: A story about two awkward people saving each other
