I Win by Doing Nothing in a Substitute Romance [Female Alpha, Male Omega]

Lu Ruanruan is a lazy Alpha whose greatest wish in life is to coast to victory. But in reality, bad luck is always on her heels, and she's completely broke. The day she was falsely accused of being a substitute and lost her job as a paid companion, Lu Ruanruan got angry. Driven by her intense resentment, she got a System. The System requires her to become the female substitute in ten ABO novels where the male lead chases his wife after losing her. If she can coast to victory, she can make her wish come true in real life. Lu Ruanruan: That sounds easy. Coast to victory? I'm in! But later, the plot in each mission world starts deviating in all sorts of strange ways. The missions get upgraded to hard mode. * World One: The School Hunk's Substitute Lover Lazy Lu Ruanruan: The top student forces me to study. If I don't study, I don't get to eat. Somehow I end up a top talent in high tech. World Two: The Apocalypse Big Shot's Older Sister Lazy Lu Ruanruan: My sweet little brother is about to destroy the world. How do I treat this psycho? Help, I'm desperate! With each world she transmigrates into, Lu Ruanruan inexplicably gains a new skill. And each skill feels as though it was hers all along. After emerging from the quick transmigration worlds, having been through the wringer, Lu Ruanruan returns with her skills maxed out. One day at a bar, she runs into her former employer, "Boss Huo." A male Omega sits in the dim, yellowish light, his long legs drawn up, his features cool and sharp. He lifts his eyes to look over. Their eyes meet, and the distance between them fades. Lu Ruanruan freezes in place as chaotic fragments of memory rush together in her mind. Like scenes passing before her eyes, she sees another version of herself. She walks up to the man. "I'm sorry I'm late." A faint haze passes through his eyes. "It's okay... As long as you remember." Content warning: The male lead is the same person in every world, and there are lots of personal worldbuilding details. I can only give away the final twist: the heroine is an incredibly powerful big shot. The story has a huge twist, so the pacing may be slow transmigration. Theme: The lazy heroine is a big shot.
