'It's just a robot, stop being ridiculous!' 

But what if it's not 'just a robot'? 

What if it's the start of his life?

The life he never knew he had?

Sehun is a robot inventor who invented Baekhyun,  the robot. Sehun thought Baekhyun is just a robot that knows how to talk, and Baekhyun thought he's just another robot that's made for sale.  

Maybe, just maybe, things are not how they thought it is.
