Flabbergasted
As Yoshiko began explaining, Lucian quickly realized he was wrong in his conjecture. Lily did not go overboard at the auction, she had a reason to spend that much.
However, either scenario would have been fine with Lucian. He would not have minded. Money, at the end of the day, was temporary, it could always be earned. If one did not spend money, then what was the point of earning it? To horde it like a greedy Dragon just for someone to come by and rob them of their wealth?
As long as Lily had fun, then that was all that mattered. And judging by the way she had skipped to Yoshiko's office, it was clear to him that the little chaos creator had loads of fun.
Furthermore, it was not as though he did not make gains from this trip. The potential long-term business contract with Yoshiko, four Grade 1 Magical Beasts, a map to a Secret Realm, and lastly, he acquired a subordi… a disciple made the trip worth it.
