Transmigrated to the 80s: Tightly Hugging My Childhood Friend Big Shot and Not Letting Go

Su Ying woke up to find out that she had been living in a period novel, and she was the original book's top "love-struck idiot" female supporting character. To pursue and please the male lead, she gave the job her parents left her to the male lead's sister; she ruined her eldest brother's marriage, causing his fiancée to marry an abusive man and be unable to conceive for life, and her eldest brother also turned against her, never speaking to her again. To prevent her second brother, who had gone to the countryside as a "zhiqing" (sent-down youth) in her place because he feared she would suffer, from returning to the city, she sold his quota to return to the city to someone else. She even found a village woman to get pregnant with his child, binding him to the countryside for life, which led to her second brother being tormented to death by that woman's family. Not only that, she was also gaslighted (PUA'd) by the male lead's vampiric family, selling the house her parents left her to support the male lead through university. While she worked in her hometown to take care of the male lead's family, the male lead used her money to buy a house in the university city and married the female lead, living a happy and fulfilling life with children. After her remaining value was exhausted, she was sold to human traffickers by the male lead's family and ultimately died tragically.

After rebirth, Su Ying decided to stay away from the male lead's vampiric family and treat her loving parents and brothers well. But... why was her rebirth timing wrong? She was reborn on the very night she slept with the wrong person, who happened to be her sworn enemy childhood friend... Su Ying didn't care anymore. Her childhood friend was the provincial top scholar, a military academy student, and a future military big shot. She'd just hug his thigh first and worry about the rest later...
