Time has passed, enough for Shin to recover from his physical injuries. That's not all though. I reckon that's Opium, so he's dealing with either pain or PTDS, or both. The scenes around the Opium and the organisation of the event (the blue roses) are in the present. Anything else where his physical injuries are still visible are flashbacks or memories.
In any case, he's suffering like hell.
when she said she didn't see Sora since. I truly thought Sora died.
I'm so happy they had their happy ending.
This was really amazing, such a beautiful story.
