jin's narration: i felt tired so i slept.

the cherry blossom trees that i saw while walking right before the accident.

the petal of the cherry blossom in my palm and the wish that i made right before the accident.

those were the only things that i could dream of.

as it felt real, i couldn't do anything but to wake up.
