The common men and women found in the hot spring town meet soon, and the "mixed bath monitor experience" is the first time. How many minutes until an instant couple takes a bath during a bath? 3

It's the third shot! It is called the mixed bath monitor experience of the general and women in the hot spring town, and only two couples bath! At first glance naked! It is not possible to do it though it is not such a thing. Does the person who is neither a lover nor a couple get the fire while bathing?
