First is necessary to point that this third and last school year may be actually just six months. Classes are not mandatory for third years during second semester, so maybe we'll see Tomoko working for her life and future outside school during the last chapters, or maybe Nico Tanigawa may choose rush to the graduation ceremony.
The Tomoko who starts her third year is very different from the one who started her first year. She is still shy, but we can say that her social phobia was cured. She could have now courage and strength enough to talk with strangers. My first doubt is if she will go talk to strangers, of if she will NEED to talk to strangers. There's the possibility that she will be put in a class without the friend she made during her second year, what would be better for her, forcing her to try a bit more harder.
What ocasional characters that we already seen em past chapters may reaper?
Will Tomoko make a male friend during first semester?
That girl who felt ill during her admission exam, will she be Tokomo's first kouhai?
Will Tomoki stop being ashamed by her sister and will start to talk to her at school?
Will Uchi stop stalking Tomoko to finally become a regular friend?
Will Nemoto become more intimate with Tomoko and share her hobby more?
A certain thing that I was wondering the other day. What if "something" happened in Tomoko's life? Certainly, would be a mystery to put some tragedy in Watamore, but I stop imagining if Tomoko would be able to handle something really serious happening in her life.
