They both changed, to quickly for each other. Yukio focused only on school and had no time for others, while Nova was more outgoing and popular.

So when they graduated and became exorcist, Yukio blocked her on everything, ignoring her, basically ghosting her. But if only Yukio would’ve known that nova wasn’t as perfect as he thought.
