Gray usually dined with his pack of loud and ludicrous brothers, unlike today, when he went into a bustling Thai restaurant. He didn't necessarily want to be alone, it's just that, it was already midnight and he thought might as well not bother his friends who were probably already sleeping, or cuddling, or you-know-what. He knew they wouldn't say no to Thai, and most likely he would just hear them complaining and teasing him about bothering them.
So there he sat, by the window, quietly humming an invented tune as he waited for his food.
