Not to ruin the sad mood

I can't seem to remember that nor find it. Can you clarify it more?

My mistake, it was the first three chapter where yu yang was introducing himself and then starts narrating it a bit. When he talks under the text box he starts to cough and then starts talking about things that would happen.
Kinda think I’m I over analyzing I’m not sure.

Ah right had forgotten about the narration being his future self. Though i think the things he says are more examples of the hardships that they will go through.. All we can do is speculate xD
