Once the bus stops at a late-night service area, Chitose (with her maids) is eager to find any rifts between Nasa and Tsukasa's love. Indeed, she thinks that even small problems can put an end to a male-female relationship. Also, she believes that there is no need to cause any of them. In effect, are these problems starting on their own? Yes, but as soon as a problem seems to appear for real, making Chitose all excited, it disappears in a blink of an eye. Why? They turn every little problem into a new and unique way of flirting, making Chitose's plan more and more pointless over time. Will she be able to hinder their relationship?

Nasa's apartment has completely burnt down. Have they lost everything? Well, nobody got hurt and the plant commemorating their marriage is miraculously intact and Nasa is very relieved. And what about the other stuff? Tsukasa has married a provident boy and guess what? He is already organized and his bank book and other important things are in a safety deposit box. Still, what can they do about a new place?
