Ultimate Series: Something Seems a Little Off

After breaking up with her boyfriend, Huang Bailing was so heartbroken that she drank herself into a stupor. She never expected to get caught red-handed by a System and transmigrate into the world of KO Series. Even more surprising, this System had quite a personality, so she named it Little Cutie. To go home and help the System complete its transmigration quota so it wouldn't be deleted, Huang Bailing has to work hard to finish her mission before the Silver Dimension storyline ends. When the story begins, Huang Bailing discovers that she's crossed paths with someone else who transmigrated into the same world. "Are you sure your mission is to be friends with the protagonists and not to be a player?" Hiding beside a tree, Huang Bailing watches the other transmigrator exchange loving glances with one protagonist, then turn around and try desperately to win over another. She can't help asking. "No, my mission really is to be friends with the protagonists." A slightly mechanical little girl's voice rings in her mind, equally confused. "Maybe everyone's mission is different?" Though Huang Bailing remains skeptical, she still has to continue her mission. Since she can't switch to a different storyline, she keeps out of sight to avoid being discovered by the other person, and quietly befriends the protagonists, following the principle of friendly interaction. But as time goes on, she increasingly feels that something doesn't quite add up if she thinks about it carefully... [Things to Note] 1. Multiple roles for one person, a self-indulgent creation, told in first person. 2. Includes the three original series: KO One, KO Family, and KO Three Kingdoms. 3. Some couples may be broken up, or they may not. 4. There will probably be more original plot than the original series, though the original plot will still be included. 5. I'll keep working hard to improve. It'll most likely be a Mary Sue story with an overpowered golden finger, but I'll try to make it feel normal and avoid awkward writing.
