Bocchi The Book

In Shuka High, Bocchi's class out of nowhere gets assigned with another class in a different japanese school to be penpals. All she knows is that her pen pal is a guy, and that she has to write first.

What could this possibly lead to? A chance for bocchi to talk to someone without being an anxious mess?
Perhaps forming her first friend outside of Kessoku Band?
Getting more confidence with people in real life?
Maybe even this friendship blossoming into more??????

Or will this just end with Bocchi tripping up and ruining her chances again?

With a lack luster description like this, what is the author on, thinking this will get readers? We don't know, but I want it, find out what a lack of a planned out story does to a person by opening up this book and finding it's not all that shit. [Please]
