So, let's talk about 同士どうし. 同士どうし is a noun that means "fellow; mutual; comrade; companion", and can also be used as a suffix. When we attach 同士どうし as a suffix, we turn 「(noun)」 into 「(noun)同士どうし」"fellow noun(s)". But watch out, because this one is usually just for people. (We'll discuss exceptions to this later.)
