In her previous life, Yuan Tang was a qualified eldest sister, supporting four college students in the family; a competent daughter, taking care of her seriously ill parents; a generous elder, after her parents passed away, she worked hard for her younger siblings' children...
Even though she died of illness alone on New Year's Eve, Yuan Tang never resented her unfair fate.
Until -
when her younger brother was sorting out her belongings, he took out a blurred admission notice from a rusty iron box.
"Sister, actually you and I both got into high school, but my parents didn't let me tell you."
"Sister, don't resent my parents, it's not easy for them either."
"Sister, I'm sorry."
Looking at the paper being devoured by the flames, Yuan Tang suddenly felt that her life had become a joke.
When she opened her eyes again, Yuan Tang was fifteen years old again.
Her father was smoking a pipe, and her mother spread out her brother's admission letter, with a sad face: "Da Ya, you didn't get into the No. 1 middle school in the county. It's not easy for our family, and it's hard to support you for another year. You are the eldest, so you have to suffer more... Or you can go out to work."
Yuan Tang stared expressionlessly at her silent father, her expectant mother, and her brother who looked a little uncomfortable.
"I won't go."
If she were to live her life again, she would never be the good sister that others talked about.
She wanted to live for herself.
Starting from that notice, from a small country to a big city, the road ahead is long and bright.
