I'm completely inlove with After School's "Someone is You", from their "Love Love Love" single album. I have no idea what they're singing, but all I know is this song is absolutely well composed and filled with beautiful harmonies.
After School is a kpop group that has some really fun dance/pop and r&b songs. The members also participate in variety shows, and star in dramas. They're very versatile, however pretty underrated in their country. Anyways, After School is a awesome group and I recommend you kpop lovers check them out and purchase their music from yesasia.com
Check out "Someone if You" and also my favorite music video "Bang":
