It is an unconscious action, you think to yourself, referring to the way he keeps a wall around himself. He's been raised to make himself everybody's pleasing, perfect gentleman, and it is with no effort that he can charm and coax and captivate and deceive, because everything about him, layer after layer after layer, is too fake to be real.
Or, perhaps, it is his falseness that makes him all too real.
It disturbs you.
"Kyouya can be like that, sometimes," Hunny-senpai says thoughtfully, his eyes half-closed as if in contemplation, and even if you want to ask him to explain (which you didn't), he adds that he can't put his finger on it.
You wonder what 'it' is.
You try to build your own walls to protect your castle, but all you can manage is to create a moat and a drawbridge that is lowered for anyone and everyone, even for him, and his defenses seem to increase in size until you are sure that the wall can reach the sky and the moat is too wide for anyone to cross.
When you find it in your heart to finally accept him, you are not surprised that he keeps pushing you away. And it is an unconscious effort in your part, even if he does not believe that you can be so natural and oblivious and not at all like him, that you can claw your way through layer after layer after layer of skin and lies and smiles and sweet deception, until you manage to touch him where he does not want anyone to get close to --- his heart.
(He touches his chest and his jaw tightens before he looks away, as if ashamed to be caught, and you smile at the flicker of annoyance and something too soft to be called anger in his eyes, asking him if there is anything you can do to help him.)
(He narrows his eyes and tells you to go away, and, before you do, you realize that the walls that he has built are falling to pieces slowly, and you're not sure if you like it or not, but it's a start.)
One day you wake up next to him, and there are no castles to protect or women to charm. There is only you, and him, and the space between you is still wide, but it doesn't matter.
There are no more walls to destroy, because they have all crumbled.
Always forgive your enemies; nothing annoys them so much.
