Ten years ago, when the three of them decided to start a business together, Nao was the one who suggested that they start a company. When they consulted with them first, they found a good building and decided on where their offices should be. Nao wanted to start the business, but she got into an argument with Kiichirou, and they ended up divorcing. When he heard of this, he was shocked and decided not to go into the business. He tells himself that he is the only one who has been saved by his friends, and he is confident that he will be the one to be saved. He says that he does not know anything about the marriage and divorce, and that it was not like he suddenly wanted to hear about it. He wishes that he were the person who got dumped by her, because now that he knows the past, he can use it to his advantage.
