Transmigrated into a Book as a Tenant with a Baby, but I'm an Expert at Baby Talk

[Romance + transmigrate into a book + fluent baby talk + a heroine who doesn’t overthink] Su Yu, who has terminal cancer, falls and dies while applying for a nanny job. By accident, she transmigrates into a CEO romance novel as a doomed cannon-fodder side character who shares her name. In the book, the original Su Yu is meek and obedient. Her scumbag boyfriend manipulates her into dropping out of school to put him through college, only to announce that he’s marrying a rich heiress as soon as he graduates. The baby, who is only a month old, also dies of a high fever a few days later. Heartbroken, the original Su Yu falls into depression and dies. Armed with a mastery of baby talk, she’s going to tear the scumbag apart, kick the white lotus to the curb, and charge ahead on her path to entrepreneurship until she becomes a top-tier childcare expert. Su Yu’s ambition: a successful career and a happy love life. An’an: Mom gets both! Su Yu looks at the young ladies and gentlemen from wealthy families gathering around her and smiles. “No, Mom gets the whole lot!”
