A Cannon Fodder's Self-Awareness

My new story, I Want to Sneak Into Your Heart, is underway! Come on over for some sweetness, lovelies! New story blurb: [Goofy blurb] Gou Ming hates playing games with strangers, especially girls and young masters who start whining at the slightest thing. Gou Ming: Why the hell am I playing nanny in a gunfight game?! Yu Caocao can't figure out the game interface, so all she can do while playing is whine: I can't get in the car. Gou Ming jumps out of the car: It's fine. You can walk to the safe zone. Teammate: ??? Aren't you embarrassed? The male lead talks too much, and the female lead is a sweet, silly airhead. Story blurb: Su Xing transmigrates and discovers that she's not only an idiot, but also a disgraced divorcee. Once she learns what happened, she decides these ancient people need some ideological reeducation. Then Su Xing discovers she's transmigrated into a melodramatic substitute-bride novel. She's the nominal "fiancee" who was replaced by the innocent, sweet heroine and made to marry the male lead. Her only appearance in the entire book is her name. [First person] Theme:
