Hello, it's me again 
Ever been a situation where both had to just let go not because one was caught cheating, not because any really wanted it to end but on mutual understanding, though painful but the best choice moving forward to avoid future disaster.
Yeah that's what is it. It's an imaginative concept, showing both faces between a broken heart.
The tears on both faces represents the heart of both crying out even as they depart..and usually, it's always a silent cry.
My God console those who are currently going through this stage... AMEN.
