The girl was singing the same hook and I'm not sure if she was ending each with "without you" or "i love you". Either way, she ended the hook with "you" and it was in english.
There was a guy rapping the song and the music video seemed like either it was a love song/heartbreak, and it was very popular in the 2000s. I discovered this more towards 2008-2009 but I'm sure it was out for a while by that time.
There were two versions, the asian version and an english version of the song, but I think the english version was still not as coherent.
