Did My Aloof Sword Immortal Master Lose Me?

Years ago, the Heavenly Heart Sword Immortal "left behind" her disciple and resolved to ascend to immortality, only to be betrayed at the final moment and fail in her ascension.

With only a trace of her spiritual essence remaining, her contingency plan activated, and she was reborn. Upon her return, she followed the signs and found her disciple once more...

After all these years apart, did her disciple still love her with the same devotion? Had his swordsmanship improved? Had he become a renowned genius of the sword?

Full of hope and regret, the Sword Immortal found her disciple again, only to realize in bewilderment...

Her disciple had indeed grown up well, and had found someone he truly loved. So why did her heart hurt so much?
