Anyone remember know this song?

So I just came across some old Korean songs I listened to as a kid and I remembered one other song I wanted to see again. I can't exactly remember the whole thing, but I remember it's a Korean song for sure. And the MV was about a pair of twin sisters that loved the same guy. And the guy was in love with the 'nice' sister. And the other sister was jealous and went to meet the guy as her sister, b/c she killed her sister or something. And the guy couldn't tell the difference and he didn't know his girlfriend had died. That's about as much as I can remember. But there was a fire or wreckage in there somewhere. So if anyone can recognize this song and tell me, thanks a lot. Btw, I was listening to the song a lot when I was probably about....7-10 years old. I'm 16 now.
