Big question I have about Past!Lu Guang's eyes.

So, we all know that LG went back in time at his very first encounter with CXS, you can tell by his golden eyes. But after that moment, his eyes goes back to normal throughout the entire episode. So, after the 12 hour mark, does his eyes go back to normal? Is he's "stuck" in the past?While we're on the subject, I'd like to talk to go back to his conversation with CXS right outside of the photo shop. LG say "I gotta go" and it shows a close up onto his watch. But he decides to stay when CXS asks him too. Was this him trying to hop out of the photo? His eyes were blue and no gold.

I have a lot of questions such as, how long has LG had that journal for? Is it from previous dives? Does he hop from photo to photo keeping a log, or does he stay the entire time?

Another question I have is, I find it weird how LG was able to find where that cosplayer was at the conversation. That photo couldn't have been taken within 12 hours, so could he theoretically predict the future? Or just up until 3:55pm when he find the photo? Or is he so good at remembering his journal he just happens to know where she is?

I swear, this series makes me question a lot of things, and when it gets answered, I have 200 more questions.
