I still don’t get why he’s trying so hard to cover up all these crimes and to tell all these stories. Wasn’t he gonna kill himself in the first page of the first chapter?
Hina was the one who told him to do the 100 stories thing. Since this is a Japanese urban legend we're talking about she perhaps told him a version where once you've told 100 ghost stories a real ghost will show up and kill you anyway, so you don't have to jump through the window right now. She did it in an attempt to stall his suicide, perhaps to buy herself some time to get closer to him because she thought "I can fix him".
The lamp is uncovered today. I didn’t expect the ghost story to be so hopeful. Lots of mentions of Hina and even a smile, wow. for how many times we’ve seen the parents they’re still such a mystery
