The same fact seen from different perspectives that give rise to different perceptions. The sum of the four images represents a moment of intimacy in a kind of circular dance of two lovers who seem to live in the present united by their lips oblivious to everything. Because there are kisses able to stop the world and make it clear that the after does not exist. Kisses that close your eyes can turn off the sunlight to give you privacy and make you turn inside a chasm you would not want to escape.
There are many types of kisses, but this one in particular, with everything that at least has transmitted to me from all the visions that he has presented to me while I was working on it, it seemed worthy to be immortalized with all its "abysses".

P.S. If I had to say what I would say this box sounds like, it would be at the piano of Yiruma and her River Flows In You.
