Hi everyone. I'm currently watching Korean series "Beautiful my lady". Unfortunately, it's not subbed and I don't speak Korean (I'm from Europe). However, I manage somehow. One thing is unclear to me. There's a guy (Sang-min) living under the same roof as the lead female character (Yoo Seon Yeong). At first I thought they were related (a brother or a brother in law), but when he proposed, I realized they weren't. She turned him down and married a handsome boxer. And guess what! They all kept living in the same house, the newlywed couple, two kids, the bride's father and the guy, the GUUUY. Who is that guy? He happens to work with her father in the hospital. But seeing him in his slippers, having breakfast with the family every morning gives the the creeps. Please, untangle this for me. Thanks and luv you!
