Kito made a bad investment and drove himself into debt, 5,000,000 yen. He was persecuted by an insistent creditor almost everyday. One day, he saved a lady who was CEO of a big cosmetic company by accident. He expected her of something good one in return. But she just gave him some cards of baseball players. He disappointed so much. But these cards were value if they were complete. He missed 3 cards which were the most valuable. If he had 1,000,000 yen, he could get these 3 cards, and he could sell all cards by 5,000,000 yen. And he found strange job that was good for his situation. It was that staying in closed beach house with 2 other strangers for 2 weeks.
