After I Transmigrated to the 1980S, I Refused to Live a Life of Cheat Codes

[1980s setting + building a career + hard work + sweet romance + no golden finger + golden finger] When Su Wan wakes up, she discovers she has transmigrated to 1982, a time of shortages and hunger, without a single golden finger. Her awful relatives come around to mooch off her, her honest parents let themselves be pushed around, and life is unbearably hard. Luckily, her grandfather told her stories about the decades to come from the time she was a child, so she knows all about the opportunities brought by reform and the latest business trends! No System, no pocket dimension. She is her own strongest golden finger. She stocks up on good stuff and takes on her awful relatives, seizes opportunities, and makes a fortune. While everyone else is still worrying about having enough to eat, she is already living in luxury. But what is with the man beside her? Dating her is one thing, but now he wants to marry her too! The nerve!
