After Lucy suddenly left the dining table, Arthur attempted to follow her, but Zoe stopped him.

“When Lady Alrn acts strangely, there’s usually a reason for it,” she explained with an awkward smile.

Arthur was about to refute Zoe’s statement, but upon reflecting on it, he realized she was right.

Since coming to the academy, he had many opportunities to observe Lucy.

He had questioned her various behaviors, but looking back over time, he found that most of her actions had reasons behind them.

Even the fact that she called him the 'pitiful prince' was likely not without some cause.
