Best Friends Transmigrate Together to the 1970s and Divide Up the Heroine's Luck

Two modern best friends transmigrate into a period novel and become two cannon-fodder supporting characters. One becomes the village chief's daughter, taken advantage of at every turn by the original heroine. The other is an educated youth sent to the countryside, whom the original heroine manipulates into falling out with her family. Through fake sob stories and mean-girl tricks, the original heroine steals their job assignments, fiances, and every opportunity.

After they transmigrate, the two draw a clear line and team up to make a move! They seize the heroine's pocket dimension, save the leader's biological father, snatch the factory's permanent positions, make the original heroine's terrible man their own, and win back the male lead, the fiance who was stolen from one of them.

The original heroine: "This isn't how it was supposed to go. I feel like I've lost something!" The heroine sneers: "Because all those opportunities are ours!"
