I can say with confidence that Heenain is my favorite female Korean singer. Loving You (1,2,3,) is the third version of the original song 1,2,3 and will be on her new album The Acoustic.
The lyrics were written by Donnie J and 1sagain (who released their own song entitled Depressed), but Heenain truly makes it her own with her angelic voice.
Loving You(1,2,3) is love personified.
