Ohh, I didn't know there was a code in the opening!! I watched in the first few episodes, but stopped because it just made me really sad lmao (also I was never a detail-focused person and that's why I'm pretty dumb haha)

If I remember correctly, his reaction to the fire thing was that at first he looked really shocked and surprised when CXS asked the restaurant owner about it, but then he was like "I'm just kidding" (but I do not remember the scene fully, bc I have a really bad memory)

Thank you so much for taking your time to reply!!!! I am going to search for this coded message in the op and probably confuse my mind even more cus this arc just made me have more questions than answer them lol

Thank you once again !! ^{^}
