Two people can be exactly the same, yet be polar opposites. Sehun has found his opposite but realises how they are too similar. 

Like the cold breeze of pluto you pass

Me, the fiery jupiter rush.

You can freeze the Sahara

And I can melt the ice caps.

Yet, we are as alike as

newborn babes of the same mother.

You could be gas

I could be ice.

And we'd never be too far from n'other

Now I find myself in you 

To look in your eyes, is like looking through a magic mirror.

In them, I see my soul.
