The name of an anime character in "Death Note" which was taken on by K-pop idol Kim Myungsoo of the band Infinite. L is a mysterious and cool guy while Myungsoo is shy and sweet.
L is Myungsoo's evil twin.
Aish, they're making fun of Myungsoo, but they fail to realize that it was L on stage last night. Ugh!
Omona! Did you see Myungsoo's abs in that see-thru shirt?? GAH! I'm dying rn... Dude. That was L...duhhh!
