Monolids are quite the beauty trend in South Korea and K-Pop in recent times.
Back in the earlier days of K-Pop, double-eyelids were considered to be the facial feature that defined a "beautiful" face, but times have changed and there are many people who prefer monolids these days.
Bottom line, whatever the eye-shape, it doesn't really matter, as the outdated assumption that monolids can't be beautiful is no longer the case.
Any how, there have been a few cases where K-Pop idols tried out double eyelids for fun.
But to be honest, it's fortunate that they never got them done and they remained just as they are because they look so much better in their natural selves.
You can check them out below.
JB tried it out before, but really, we're really glad that he never got them done permanently through surgery. While he does look good with them, it's just not the same as his natural beauty.
Hoshi did this before because a fan asked him to try it out during a live broadcast. He laughed at the results.
