Dressed As the Male Protagonist’s Stepsister

Yu Qian entered a novel written for her by her best friend.
However, she is not the heroine, but a drag bottle who married her mother to the hero’s house.
Yu Qian said, none of these matters!
The important thing is that in the book, her mother is still alive, and she has finally become a child with a mother again!
In her life, she just wants to be a good mother and daughter, and occasionally watch the male and female protagonists fall in love.
But-
Who, aren’t you the good brother of the male lead?
Why are you sticking to me?
What?
you like me?
What?
you want to marry me?
Damn it!
