For Hitomi, a new graduate office worker who had the looks and style that everyone envied, and who was surrounded by handsome men and rich people during her school days, it was a great pain to spend time under one roof with men who had no delicacy. The training trip is only for one day... If you endure it, it will be over soon... The ugly old men bare their fangs at such a beautiful body with narrow eyes! Irama intruding into a hot spring, a hellish banquet, a fierce piston wheel that violates a beautiful body, a night that doesn't feel at ease even in the middle of the night.
