waitt how comee? Sobs
wait do you mean shinpei or kotaro
*theories below, not spoilers*
Shinpeiii, here me out... *.
1. Old guy is holding letters that are speaking from a female POV (SO IM ASSUMING THESE ARE THE FLS PAST LETTERS TO HIM)
2. Old guy is crying reading the letters - likely reminiscing his time with her/love for her
3. Old guy is in a field of fireflies
SO SHE DIES BEFORE HIM??
actually looking back at it why does the side profile look like her dad but older? IDK TAKE IT HOW U WANT
OH SHIT NOOO THE OLD WRINKLY GUY AT THE BEGINNING CRYING WITH THE LETTERS MUST BE HIM NOOOO
