I have no idea what they are saying in the video. XD But the title says something about being the best “Idol Fake Couple.” I haven’t thought of this “couple” before but I remember Zico once mentioning Dara in his freestyle rap. Click this link for the video of that one. ^_^

@koreanposts those are the most popular couples outside of Korea, there, those are seldom mentioned or cared for.
They should’ve put DaraGon or JaeDara or DaraHae or ChanDara or LuDara instead. They’re the most popular. Anyway, i’m fine with them coz’ Zico is a talented rapper and Dara fanboy. Any ship is okay. lol
