OMG this is so embarrassing, I nearly committed another faux pas in blogging! - when they said that the song was sang by 2AM's Jinwoon and Changmin, I thought it meant 2AM's Jinwoon and the other Changmin (i.e the only Changmin I know, the DBSK one). It wasn't until I finished my translation did I realize that Changmin referred to 2AM's Lee Changmin. Whew! Close call >_<"
On the song, I admit I didn't really like it at first and I was only interested in translating this for the DH factor (I wanna know what the song means when it comes out in a scene). But after hearing it for more than 30+ times (due to translation works), it sort of grows on you. I especially like the chorus (the parts with the echoing of the BG singer). It's catchy and sweet.
