Rayne has a routine, a plan.
He lives life according to this routine. A few times a week, his routine allows him a few hours to hide away in his diner.
Everything is always the same in this diner, even the variances are consistent.
That is, until the gray-haired manager hires a new waiter who moves about like a tornado. This boy does not know Rayne's "usual" or his proclivity to be left alone so he can watch and study the people living around him.
This new waiter disrupts his routine in all the worst ways and Rayne can't help but hate him.
He doesn't seem to care, however, continuing to disrupt Rayne and see Rayne and pop Rayne's bubble of safety, and ask Rayne questions that he doesn't want to answer.
It was all quite aggravating really.
