I love how the final chapter plays with the timeline one last time. The obvious intention is to trick the reader into thinking that this continues from the previous chapter but you can see from the clothes she's wearing that this is actually setup for chapter 118. You can see from her clothes >>281505474 that when Hotori gets erased from existence she gets sent to the alternate reality.
I also like that this chapter ends on one of the more subtle buildups in the manga. Hotori has been writing that play for a long time and seeing that passion in real use is cute. Then seeing her become a writer in the epilogue is so satisfying. She didn't know how to finish her play but she clearly grew a lot between those two points. I love it.
