Ota had been having a lot of trouble sleeping lately. But not only that. He couldn't find inspiration, everyone was getting on his nerves, and he didn't even have time to eat with all the work he had to do at his gallery. He had gotten more gloomy than normal and basically had an angry look on his face 24/7. The other bidders noticed and told him that he should really get checked or something, and since Luke wasn't available.. he had to go with some doctor he didn't know of.
