第14話: 日向荘の財政危機の中で、ナルの片思いの相手が東京大学の教授に

14

There is a financial crisis at Hinata House: if the residents don't come up with 67,000 yen in three days, the utility companies will cut off all services. Keitaro ends up working for one of Tokyo U's scientists, not to mention his hyperactive daughter, but doesn't know about the old connection between this man and Naru. (Source: Wikipedia)
