They're perfect. 

Sehun's the perfect son and Luhan's the perfect daughter. 

Their mother bakes cookies and dances around while she sings along with the mockingbirds. 

Their father is a successful businessman who regularly donates to charity and helps the community in as many ways as possible. 

But their family was built on lies and pretences.

Their foundations have always been weak their lives are crumbling on the inside. 

They're perfect - but only on the outside. 

Sehun's a terrible son and Luhan's not a daughter at all. 

Their mother bakes cookies to fuel her addiction and she sings along to the songs in her head.

Their father is successful at only one thing - exploiting the lies and gullibility of others.
