Becoming the Teacher of a Campus Novel's Male Lead

I've abandoned the old upcoming story, _(:з)∠)_. If it's not your thing, feel free to remove it from your collection. After Becoming the Male Leads' Teacher in a School Story Blurb: On his first day reporting to school after passing the public teacher recruitment exam, Xie Ying transmigrates into not one but several formulaic, melodramatic school novels! He ends up as the cannon-fodder teacher to all the male leads! Male Lead No. 1: A twisted, gloomy psycho with an obsessive possessiveness toward the heroine, who tries to imprison her. The cannon-fodder teacher gets framed for accusing the heroine of cheating, and Male Lead No. 1 ruins his reputation. Male Lead No. 2: The school bully, hot-tempered and violent toward the heroine, causing her to miss the college entrance exam and end up washing dishes in a restaurant. Male Lead No. 3: A heartless playboy, a notorious womanizer. He gets the heroine pregnant before marriage, leading her to have an abortion, fall into depression, and attempt suicide several times. Male Lead No. 4: In love with his first crush, he treats the heroine as a substitute. When his first love comes back, he breaks up with the heroine, causing her to do poorly on the college entrance exam. He also toys with her so badly that she misses her loved one's final moments. After reading all the stories, Xie Ying can only think how outrageous and painful they are. Why do these melodramatic, angsty school novels even exist? Can't you just study properly? You're all high school students! So Xie Ying diligently follows the plot, focuses on teaching quality, and lectures the male leads on morality. If all else fails, he brings out the golden rod. After all, a little golden rod makes good people. At last, Xie Ying looks at the male and female leads, now back on the right track, and smiles in relief. Then a handsome man in a wheelchair appears before him and asks, "Would you be interested in becoming their legal guardian?" Male Leads 1, 2, 3, and 4: "Uncle, uncle, older cousin, older cousin, please don't!" Xie Ying's smile freezes. Looking at the man with so many impressive qualities stacked up, he can barely breathe. He starts pressing his philtrum hard. "Get me a respirator, quick!" Premise: Teachers are the engineers of the human soul.
