The King's Face is heating up, and star Seo In Guk is sizzling! Before his big splash in the acting world with Love Rain, Seo In Guk was just a sexy singer like the rest of your K-pop favorites. Seo started out with his debut album featuring the song "Love U" (aka Saranghae U) in 2009. He continued to please listeners' ears with the addictive singles "Broken," Shake It Up," "Tease Me," and more.
