This is purely the author's imagination, please ignore any unreasonable things.
In her previous life, she was a queen, sitting in the Sixth Palace, but she longed for the light of an ordinary couple.
In this life, she is an embroidery shop girl with a poor family, but she must be decent and have four long nails that are only found in the palace.
They say they want to be an ordinary couple, but in their hearts they care about their superiority and inferiority than anyone else.
She lives in her own world, like a vine trying its best to climb up the wall. She chose the wall herself. After climbing up, she found that there was nothing on it. It was empty and disappeared when the wind blew.
