Get to know these K-pop sensations before their first US performance. Who’s “the shy one”? Who’s “the fashion king”? The The Guide bares all. We’ll forgive you for not knowing who Boyfriend is. After all, the band’s upcoming performance at the Riviera Theatre is their first-ever US showcase. But the K-pop darlings have been sending South Korean audiences into fits of rapture as far back as 2011, when their namesake single became a staple in tween bedrooms across the country. Compare them to One Direction if that helps you, but like most K-pop groups, Boyfriend tends to eschew sentimentality for a sort of dazzling superficiality. That’s not a slam. The band’s meticulously arranged pop songs glimmer like a crowded thoroughfare aglow in neon lights—they want to make you happy, they want to make you dance. This is old news to South Koreans, but it’s time for Americans to finally jump on the glittery bandwagon. We’ve compiled 15 helpful tidbits to introduce you to the boys of Boyfriend before they hit the Riv on Tuesday, March 11. 1.
