Omg THIS. He is getting him attached to Charan so he does not leave the Palace because Charan is his little minion. I don't think the King planned for Charan and Khanin to actually fall in love.

Why do I feel like Khanins Dad who raised him knows the truth and why he took care of Khanin but after his services he was actually sent to silence him but Khanin was caught in the cross fire.
