Help, I’ve Fallen into a Chinese Textbook

When other people transmigrate, they either go back to ancient times or end up in another world. They transmigrate into TV shows or novels, or into anime and games. So why, when it was my turn, did I end up in a Chinese language textbook? I was told that the missions were just about bringing couples together and weren't dangerous at all. So why do I have to risk my life to complete them every time? Ye Min: System, are you messing with me? System: Heh. Ye Min: I put so much effort into these missions and work so hard. What do I get in the end? System: Me. At first, the heroine cried for help. Later, she saved people's lives. At first, the heroine had to watch other couples be lovey-dovey. Later, she became the one making everyone else watch. This is a lively story about a heroine who helps couples get together, then finds her own true love along the way. A sarcastic, growing heroine VS a sharp-tongued, tsundere hero who is all bark and soft-hearted underneath Spoiler-filled synopsis: Ye Min transmigrates into the world of Chinese language textbooks. To return to her own time, she has no choice but to obediently help the Department of Matchmaking complete missions and earn points. Punish scumbags, save destined couples, fulfill wishes... Give those tragic love stories a happy ending! The world inside textbooks is even more exciting! First world: Du Shiniang Sinks Her Treasure Chest in Rage Second world: He Saw the Courtesan and Burst into Tears (a cheeky, gossip-magazine-style story) Coming up: Better to Hang Myself on a Branch Facing Southeast (planned), The Girl Was Used and Then Executed, Yet the Holy Emperor Was a Lover at Heart (tentative), Three Wives with the Same Surname (tentative), and more 1. 1v1, HE, and the male lead will regain his human form. Since the original stories all had tragic endings, this one will have a more cheerful tone. 2. The author is an idiot with limited knowledge of history and writing ability, so there may be some OOC, but I promise to stay neutral and neither glorify nor vilify anyone. 3. I promise to finish all three books, no matter how unpopular they are. I'll write them out of love, so don't worry about getting abandoned halfway through. 4. Content warning: In some worlds, the heroine may transmigrate into a male character. 5. I'll add more if I think of anything. Are you little angels ready? Relive the terror of being ruled by your Chinese language textbooks!
