"The writer for Hanako's path made an epilogue for Hanako but didn't make it into the game. WARNING SUPER FEELS!!!"
"Runner's afternoon" and "Final Finale" take place after KS (Hanako's good ending). "10 July 1990" is a letter from Hanako's father. "H29 – Future" is the story of what caused Hanako's scars.
Those fill the story pretty neatly, though expect some major feels if you had some during Hanako's route.
