Just like SNSD's Taeyeon, this K-Pop idol is not usually diffident, but he posted on Instagram a photo that didn't show anything but a covered face with cap on top.
He wrote simply, "#tired" Let's have a little guess-who game: He was born in Seoul, South Korea. He is 23 years old. He was once a member of a boy band 'Xing' with U-Kiss' Kevin. He became Kara's Hara's boyfriend.
Hedebuted his solo song on February 2012.
Those who follow him on Instagram may know who he is.
