One of the best character developments is when Yuki becomes more empathetic towards Zero's situation. As Zero struggles with his bloodlust and his identity as a vampire, Yuki tries to understand him on a deeper level. This changes her from just a passive love interest to an active supporter. For Zero, his character development could be seen in how he becomes more protective of Yuki not just out of his duty as a vampire hunter but because he truly loves her. This makes their relationship more complex and interesting.
Well, a plot could be centered around Zero's bites on Yuki having some unforeseen consequences. For instance, Yuki could start to develop some vampire - like powers slowly. This would cause a stir in the school, and Zero would feel guilty. Meanwhile, Yuki has to learn to control these new powers while dealing with the fact that she is becoming more like the creatures she once feared. And all this could lead to a more intense relationship between her and Zero as they face this new situation together.
