Average boss and worker relationship

Now context: in the previous video majima was told by sera (dude in the crutch and white suit) to send a message asking shimano (majima's boss) take responsibility for betraying the tojo clan by allowing the omi alliance into to Tokyo and effectively crushing the clan, majima delievers the message in the middle of a meeting with the leader of the omi alliance, once given the message shimano kills the omi president and sides back with tojo clan, and as a result sagawa (the old man that majima talks to) in turn takes responsibility for his oath brother shimanos actions by being killed himself by omi alliance hitmen
