I Hate This Love Song!!! Who's song is that???

I am sure YG's fans know that 2NE1 and BigBang is preparing for their come back next week.
So BigBang will release 4.5 repackaged album and 2NE1 with come back album.

Today YG life blog had released a teaser image as below

So what's your opinions on this teaser image? Will this be the 2 songs title for BigBang and 2NE1 or it's a combined one? Just wait till Monday for everything to be revealed. XD
Now we can just only guess which will be the song for both of the groups:

I Hate This for BigBang?

Love Song for 2NE1?

or vice versa?

Or it's only one song for both of the groups?

YG want us to play the guessing game huh?
