She is a magician from an Eastern noble family, but she was abandoned in the Muggle world at birth.
When she was found by her real blood relatives eleven years later, she was unwilling to give up the name Cherry Leander.
And her half-brother seems to be going to Hogwarts as well.

Draco: Cherry Leander, you are so stupid!
Yun Chen: Yun Luo, you are mine.
Note: Although the heroine is relatively mature, she is still quite willful.
