#fof parallels

Bai Jiu got possessed by Li Lun and was carrying him inside his body - Zhuo Yichen also got Li Lun's powers and was carrying part of him inside his body in the last episodes.

Ying Lei died, pierced by Li Lun while protecting Bai Jiu - Zhao Yuanzhou died carrying Li Lun's power inside of him while protecting Zhuo Yichen (and all those other people).

Metaphorically and psychologically speaking, Li Lun did 'kill' Zhao Yuanzhou's younger self when they broke up and Zhao Yuanzhou's timeline turned into a very distinct before/after, disconnecting him from both his past and his former happier self (thanks @kseniyagreen for pointing this out).

And, in a way, Ying Lei sacrificing his life for Bai Jiu is very much similar to Zhao Yuanzhou sacrificing his life for Zhuo Yichen during that freezing scene when he still went after ZYC to save him.

Also, these two slightly mirroring scenes.

And while we're talking about parallels - there's this hint to Zhao Yuanzhou being the reincarnation of Ying Long even before we see him. This straight bloody line has been bugging me for a while now :D
