[Third-person narration]
I'm Lu Yu. As the personal disciple of the righteous path's leader, Perfected Qingxu, I've always been Yunluo Mountain's most "upright and impartial" senior sister.
I've never liked Master's youngest disciple. He's spoiled and frail, and aside from having a face prettier than a woman's, he's useless.
Then one day, I discovered Master's secret.
Master doted on Junior Brother as if he were his own child. It turned out he really was taken with his looks: Junior Brother was the only child of the unrequited love of Master's life, and he looked just like his mother.
Master had destroyed his spiritual roots and severed his meridians, all to clip his wings.
Since childhood, I'd sworn to protect the peace of the Nine Provinces. Of course I couldn't stand by and do nothing. If I couldn't protect even one person, how could I protect the world?
So I secretly took Junior Brother and "defected" from Qianyun Sword Sect.
Unfortunately, Master's reputation was as legendary as his fighting prowess, both at the pinnacle of the Nine Provinces. With nothing but my own strength, I successfully became wanted across the Nine Provinces.
After all, the truth was so absurd. It was far more believable that the senior sister of Qianyun Sword Sect had lost control of herself and abducted a frail hostage while fleeing the sect than that the righteous path's leader was abusing the child of his unrequited love.
I took the blame through tears. On top of avoiding the cultivators Master sent to hunt me down, I had to help Junior Brother mend his meridians and restore his spiritual roots.
I thought that once Junior Brother regained his peerless talent and pointed his sword at Yunluo, my work would be done and I could leave.
But just as I packed my things and prepared to roam the world with my sword, Junior Brother blocked my way with a sinister look.
"Senior Sister, where are you going?"
Help! What do I do if the Junior Brother I raised has turned evil???
A pitiful, beautiful wreck in the early chapters, a sweet-faced but sinister Junior Brother later x a senior sister who's carefree and loves her freedom
