Inside the perfect house. The house of only business, nothing of comfort or happiness.
In a dusty room, a single picture is found caked in dust and dirt.
If you wipe the dust, there lies a family that fights.
The reason being, the dust will hide all of their true nature. And just beyond the door, there lies the same picture only, quite different.
This picture is clean, not a speck of dust to be seen. The only thing that is different from the other is, it's a happy family. And this is the family that others see.
It's everything a proper family looks and acts like a horrible family in the inside.
It gives the fact that, not all looks show who they are in the inside.
