K-pop boy band Boyfriend says it takes forever for them to take a shower and the house gets dirty pretty easily. That was one of their candid responses when asked what was the best and worst thing about them living together under one roof.The New Paper spoke to the South Korean men two weeks ago in Seoul at a backstage interview before they were scheduled to appear on music chart show M! Countdown.Other rare tidbits offered up included 23-year-old group leader Kim Dong Hyun saying, "The best thing is we get to bond even more, and we don't get bored or feel lonely."They also shared that they were nervous when they were in Singapore for the first time last February for a joint fan-meet with four-member girl group Sistar."It was the first time we were performing overseas, and before coming to Singapore, we were somewhat worried about how fans would respond," said Kim."But the moment we arrived, we saw fans waiting for us at the airport and we felt happy and relieved."The boys of Boyfriend will be back in Singapore for a showcase at The Star Theatre in March 2013.
