He's just an idiot... an idiot with a charming Irish accent.
Would she squeal if I pull her dog collar? Or kill me?
These two have what can only be described as a love hate relationship. Before Seiko was seen in any type of relationship with Amaryllis she was with this notorious member of the ASBO five. Seiko hadn't quite intended for it and at first had hated Nathan when he came to her high school but eventually she found that there was just something about him she couldn't help like, whether it was his bad mouth or his idiotic charm. However they did become a thing after spending more time together and are currently very close still, though Seiko never informed Amaryllis about her relationship with him.
