Nothing against filler chapters/arcs in general, but let's remember that each volume of Delusion Telepathy has around 100 chapters and the last one ended in chapter 612.
Meaning, the author will take around 40 more chapters to end this. Can we forecast the incoming detours? My guess would be:
- Valentine Day drama (ongoing)
- Nakano's results (I'm guessing she won't pass and will enter a spiral of negativity that will last a good ten chapters)
- Confession
- Graduation from High School
- Telling Toda about her telepathy and conclusion.
Valentine Day's almost over, so we can guess we won't see confession till around chapter 680 at the earliest. It's also possible that telling about telepathy will be right after confession and there will be some mutual estrangement drama, followed by reconciliation and a quick conclusion.
Given that only confession and telling about telepathy interest me at this point, it's going to be a pain to wait. I love this series, but right now Nakano's insecurities about giving him her present sound quite forced.
