He Yan as Cheng Li Su
- Cheng Li Su’s name includes "li" (meaning carp) so his clothes and some accessories (such as fans) all have carp elements. The outfits that were lent to He Yan also had carp elements.
[Episode 9] He Yan and Ding Yi Battle
- He Rufei lights the soul-calming lamp in the Buddhist temple, and He Yan kills Ding Yi in the Buddhist temple.
- He Yan is wearing white clothes when Ding Yi assassinates her, and black clothes when He Yan assassinates Ding Yi.
- He Yan stood in the curtain of the Buddhist temple, just like wearing a hat similar on the day when Ding Yi "killed" her.
- Ding Yi threw out hidden weapon, just like when He Yan threw out stone in the fight on the cliff.
- Before He Yan killed Ding Yi, he blinded him with a knife, so that he could feel the same way she did that day.
- He Yan said, "Don't do this in this life." in resemblance to Ding Yi's words to her at the cliff, "Don't be a daughter of the He family in the next life".
- He Yan used the same moves when Ding Yi "killed" her to kill Ding Yi.
He Yan remembered every detail 👏
