면 돌아오다

if or when X, come back

돌아오다 is coming back, and the conditional names what has to happen first. Some of these lines are literal: back in two hours, giving it to you when you return, there is a way back if you go. Others are about things returning to you, such as money you spend coming back around, and a younger colleague who returns your kindness. Two lines run negative, saying once you have experienced it there is no going back.
