She is the only nine-tailed bloodline of the Spirit Fox clan. On the night of the genocide, she was picked up from the blood and fire by the passing senior sister of Qingyun Sect. She sealed her true body, hid her fox tail, and lived under the wings of Shen Zhihan as a human girl.
Sunonuo thought she hid it well - when that snow-white tail quietly wrapped around the senior sister's wrist every night, she thought Shen Zhihan didn't know. But what she didn't know was that the imperceptible pause on Shen Zhihan's fingertips was the indulgence that a person who was used to being aloof learned in ten years.
They peeked at each other for ten years at a distance of a tail, neither of them dared to speak first.
Until Sunonuo's back sprouted nine silver-white giant tails, until the shadow of the ancient evil god came back, until Shen Zhihan said that rainy night with his horizontal sword in front of her: "I have been yours for a long time."
——In fact, they forgot that the spirit fox's tail can never hide its thoughts.
