'Unpaid Hot Spring Trip' is a sensual Japanese-style adult film. The allure of the main character in a yukata is extraordinary, and the scenes of bondage also evoke excitement. However, there are voices expressing concern about the high price and poor cost-performance ratio. The sex scenes are erotic, but the static camera shots are monotonous and disappointing. Opinions are divided on the acting abilities of the actresses and the overall travel atmosphere. In conclusion, for those who enjoy provocative adult dramas set in a luxurious ryokan-style setting, this film may be appealing.
