Blue Face Not Apart Red Face No Forsake is quite romantic, referring specifically to platonic yet intimate male and female friendships that shouldn't be abandoned. Here 'Blue' face alludes to handsome but loyal man friends, and 'Red' to charming yet non-romantic lady friends, symbolizing treasuring true relationships without crossing lines into romance.
