Falling in love is not in his list of goals. All his life, he only known duty and fulfillment. But as his gaze landed on certain someone, (unfortunately) you, he wanted to be selfish for once. 

Drowned into a spiral of obsession, madness consuming his mind altered to fulfill his longing of companionship... he only yearned to be loved and appreciated. Not some Gatekeeper.

He watched as he tentatively caress you, despite your defiant expression... He only smiled. 
Twisted Love, what bliss.
