She's a Mudblood, a Muggle-born wizard
She is a little arrogant on the surface, but she hides an easily hurt heart in her heart.
She is a Gryffindor, but not quite a Gryffindor. She is a bit like a Hufflepuff and a bit like a Ravenclaw.
In fact, only she knows that she is most like a Slytherin, but because of her origin, she can only be a Gryffindor in her life.
Because of her personality, she will never be welcomed in Gryffindor, only to be scorned for a while.
Because of her origin, she was just a dirty Mudblood in front of Slytherin and could only be ridiculed.
She is also a time traveler, but not a Mary Sue
She will never have anything to do with the protagonists, and she can easily be plotted by the cunning Dumbledore and used as one of his tools.
She is so ordinary, just a little worse, but she falls in love with a savior
The hardship of life, no friends, only the support of relatives far away from home
The pain of love, there is no way, no chance to get close to him and love him
Who will wipe the tears in her heart? Who will erase them? Who will expand the world in her heart?
Ps: It's true that the male protagonist is Xiaolong! The road to love is bumpy!
