I don't understand the conversations in the raw for chapter 19, but I wonder if those to kidnappers let Nanahara hear their conversation on purpose? Is it possible that Hirata wants Yashiro to doubt/lose trust in Misumi and thus hesitate to ask for help/let him know whats going on? If you don't feel you can trust anyone, it complicates things and leaves you with less options to take.
so misumi-san planed everything? he wanted yashiro dead?
