I'm always surprised by how analytical people on Rednote are
An analysis video on Rednote said that there were many places in s3 op that were missing something(possibly lu guang). For example, the screenshot here has one hand reaching towards something. Other obvious ones are the black space below one of the scenes, or cheng xiaoshi hugging the air(Lu? 🤨) at the end.
The vid then talked about how the name of the op song is 时(shi), or Time, and how the part two op might be titled 光(guang) actually, I think they said it was already an existing song? And how the two songs if maybe overlapped at certain parts can give a message.
They also said that maybe in part two, for example, a scene in the pt one op where cxs was peering inside a house, pt two might have lg sitting on the sofa, or where cxs looks around the labyrinth(?) lg might be somewhere in the second op
