The metaphor "ice-black cold eyes" in "Once upon a time" likely suggests that the character's eyes are dark and cold, resembling the icy chill of black ice. This can imply that the character is distant, unfeeling, or even menacing.
metaphor
A metaphor is a figure of speech that makes a comparison between two things that are not alike but have something in common. It is used to create a vivid image or convey a deeper meaning by likening one thing to another. For example, saying "he has a heart of stone" is a metaphor that suggests the person is cold and lacks emotion.

Oh, dude, it's like totally a metaphor! I mean, unless you're talking about a popsicle or something, then it's just literal. But if you're using it to describe someone's heart or attitude, then yeah, it's a metaphor. Like, it's not like their heart is actually made of ice... hopefully.
