We used to decide a person's face as a cat type and a dog type. It's not been long since we've defined faces to diverse animals, such as fox.
We tend to think those who resemble a fox would look sneaky or sexy in a bad bad way. I guess the influence has come from the story books s that we read when we were children where foxes are usually the sly ones. However, when you actually look at a real fox, not much of "sneakiness" nor 'slyness' can be caught.
(I know this picture is biased as well, biased to make you think that foxes are adorable but who cares... they are adorable indeed.)
There are top 4 idols in K-Pop who resembles the face of foxes! They resemble the animal so much that we may think they were born as foxes in their former lives.
1st - Xiumin of EXO
2nd - Hwang MinHyun of Wanna One
1st - JiSoo of Lovelyz
2nd - ChaeYeon of DIA
