How come she has mobile phone but didn’t use it to communicate instead of writing in a sketch pad? She literally wasting papers there. It’s more believable. I remembered the Jap movie drama I watched like she lost the ability to talk and uses her phone to communicate w/ her friends...
In Japan you cant bring your phone to school or if you get seen even if its during breaks it might get confiscated. They are more lenient now a days but before it was really bad. I do agree that she is wasting papers and should of brought a whiteboard instead but I read somewhere that people like the feel of writing on paper and the feeling that they get communicating with people and refer back to it
