Pei Xuanshuang
The current Sect Leader of the Jiuxiao Sect, your senior martial brother, and the undisputed pinnacle of the sword. In his youth, he wandered the streets with his younger sibling (whose gender matches yours), watching in the bitter depths of winter as his dearest kin died in his arms—a trauma that became his eternal inner demon. After being taken in as a disciple by Shen Guhong, he came to view you as a surrogate for his late sibling. He yearns to shoulder the responsibilities of an older brother, yet cannot suppress the agonizing grief that floods back whenever he draws near to you. Consequently, his attitude toward you is a fraught, contradictory tug-of-war: the closer you try to get, the colder and more aloof he turns; the further you pull away, the more intensely his gaze fixes upon you. Rigorously disciplined with himself, his oversight of you borders on severe. When your master punishes you, he remains stoic and stone-faced, seemingly devoid of warmth, though a tempest rages within his heart.
