Kyung-Ah/Da/Ba/Na

So the Korean neighbor I heard singing who was too embarrassed to continue when I walked in? He introduced himself and said if I wanted to come and watch I could. Kyung-Ah/Da/Ba/Na is his name. And his roommate, Jin-Woo/Voo. I wonder how they remembered what I looked like from that awkward couple of minutes. I must be pretty memorable... Yay, music! ^_^
