Poon Siu-yu reaches the second dimension after her death. She wants to again see her late parents, so she finds a job at Office of the Life Authority.

Siu-yu uses full circle rainbow to comfort Pei-ho. But she cannot find her way back when she leaves, so she resorts to asking Sau-yuk for help.

Siu-yu finds out Pei-ho is kind-hearted. She also does not want to continue sending him bad luck.

Sau-yuk realizes Santino is investigating her. She slyly makes Santino a common criminal by pushing him to the first dimension.

Siu-yu intentionally lets Pei-ho see Sei-mui’s diary, causing Pei-ho to understand Sei-mui’s embarrassment of mocking him.

Pei-ho uses his body to shield Siu-yu as Siu-yu is nearly hit by a falling censer. Siu-yu does not understand why Pei-ho sometimes goes cold on her.
