[Period setting + exclusive devotion + big shot + age gap + 1980s + transmigrated into a supporting female character]
After an accident, Nie Zhaozhao transmigrated to the 1980s. She thought that, as the only daughter in her family, life would be smooth sailing. Instead, she found herself in the body of a doomed cannon-fodder supporting character from the original story. Before transmigrating, she'd been a brash, tough girl. Her childhood sweetheart and fiancé wanted to break off their engagement, her father, newly widowed, wanted to marry again, and the dowry her mother had left her before dying had gone missing. Her old home no longer had a place for her, so she had no choice but to set out west with her mother's handwritten letter and a letter of introduction. She never expected to stumble upon the famous cold-faced northern army officer.
Nie Zhaozhao didn't dare look up. In a soft voice, she murmured, "Brother."
The man's face was cold. "Who's your brother? I'm your fiancé."
