An upset Yiming realises Jingjing died five years ago. Jingjing is moved when he brings flowers to her grave and sings for her. Jingjing and Haoliang are sent to Weavers’ Hall to spy on Di Jude and Lady Hua. Robbed of his weaver’s spot, Dai Gonggong vents his anger on Xiaowen and gets her injured.

Xiaowen saves Haoliang in time and is driven out of Weavers’ Hall by Pei Lao, whose mood swings force Haoliang and Jingjing into quitting their spy work. The CEO convinces them to join Project Zero. To help Jingjing sneak into Pei Lao’s secret chamber and install a camera, Haoliang messes up the woven fates and incites a riot. An upset Xiaowen renounces the half-hearted Haoliang as her student.

As things between them heat up, Lady Hua accuses Xiaowen of seducing her student and bribes residents into condemning her as immoral.
