Comment by Daddy's gonna buy you a Mockingbird I'ma give you the world, I'ma buy a diamond ring for you, I'ma sing for you I'll do anything for you to see you smile And if that Mockingbird don't sing, and that ring don't shine, I'ma break that birdies neck. ♡ on My Suha - Chapter 28

Unlike some people here...
I think what he is doing is weird and wrong...
Why not just take a moment with suha, have a conversation...without s e x -_- just talking to eachother and discuss their problem, 
What suha really want by example,
What directer park expect from suha
And what they are gonna do about this 
Amd not buy his little sister to spy on him like the desperate dude you are 

But anyway, ur gonna be discovered one day or another..
It's always like this.
A nasty plan can never last forever 🫂
