I adore listening to live duets. Sorry for this is in korean. I'm really oblivious with k-ballads though. But this is exceptional. Of course, two of Apink members are singing it. And one of them, my Eunji. Sigh, she's spectacular. I love her vocals. Even though she's making allowance for Namjoo to show off her vocals, she's still uh-mazingg!!! The way she falsetto/lower her notes without singing it forcefully~ Mmm. Also, Namjoo for sure tops Bomi in her clear high notes now. I love this twwoooo! They're good in duets!
