Tears.
To Kaoru it seemed like he was always crying. Always weeping over something that didn't matter. At the rate that he cried Kaoru could've filled a nicely sized pool. But even as he cried no one noticed. No one carried.
The dark.
Kaoru was scarred of the dark. Scratch that, terrified. He kept it well hidden of coarse, never telling anyone about it. It was to stupid, to idiotic in his own head to be scared of, and yet, he couldn't stop shaking.
Selfless.
That's what Kaoru was. Selfless. He put everyone in front of himself, not caring about how it could hurt him in the long run. Never thinking about himself, not even a little bit.
Shy.
Everyone could see it, even if they didn't really care about it. Sometimes Kaoru would just back off, hide in a corner, try to act like he wasn't there. He never liked being the center of attention, but because his twin liked to he always had to deal with it. Being in the spot light.
Broken.
That's how he ended up. Broken and a lone. No one even looking at him. Or so he thought. In truth the day he broke the host club had a meeting with him, to try and figure out what was wrong. They were to late though. Kaoru, having been broken beyond repair, had been taken away, to a place where broken people go. A place where the host club couldn't fallow.
