If The Theory That Cheng Xiaoshi Also Dived Back In Time During His And Lu Guang's Basketball Match,

If the theory that Cheng Xiaoshi also dived back in time during his and Lu Guang's basketball match, then I am so full of dread that means that he is going to die for real. I can't see him being alive if that's true, but I can totally see it being true.

Just...the fact that if it's true, he clearly didn't stay in the past long, and clapped out not long after. He only dived back to have that game of basketball with his new, old friend, and to say how precious it is to be with trustworthy partners in this life. He didn't dive back with intentions like Lu Guang did to change the past. He would have done it only to say something kind to his friend.

I just. I can picture a scene where Cheng Xiaoshi, realizing what is coming for him, and what he cannot avoid, echoing that one scene in S1 where he covers the walls around him with photos he had taken with Lu Guang. And then he dives into each one, one after the other in quick succession. But instead of using it to get the upper hand in a fight, he's diving in so he can give his best friend some love throughout the years, one last time, to give him lasting soft memories that will carry and comfort him in the future--much like Chen Xiao. And then just like that, he leaves.

Dive. Love you, Lu Guang. Dive. You're my best friend, Lu Guang. Dive. I'm so glad I got to be your friend. Dive. Thank you. Dive. Goodbye. I don't want to leave you without saying goodbye.
