Sensei visits the bathhouse to relax, and he is welcomed in by Uta, surprisingly. Turns out, Io has gone for a day to improve her health, so she left Uta in charge. As was expected, the two immediately begin to flirt with each other, and soon Sensei leaves for a bath. Uta, uncertain about her further actions, consult Io on the phone.
Finally, Uta takes courage and joins Sensei. She initiates an intimate and personal talk, which makes her a little bit happy, as she gets to know the man of her dreams better. As they progress, the tension gets higher and higher, but they manage to resist and go for a walk instead.
