Ep. 7: The Classic Club visits a family inn for a hot spring trip and investigates a ghost rumor.

Four Classic Club members, including Eru who planned the trip, stay at an inn owned by Mayaka's relatives. They are greeted by Mayaka's cousins, Rie and Kayo, and their family. Eru expresses a desire for a sibling. After bathing, Houtarou feels dizzy and is assisted back to the inn by Satoshi. The group, excluding the ill Houtarou, shares ghost stories, with Rie recounting a tale about a spirit in their lodging. The following morning, Mayaka and Eru report seeing the ghost. Houtarou and Eru investigate the cause, discovering it involves a yukata. Houtarou explains to Eru that Kayo secretly wore Rie's yukata to a summer festival. Because the garment got wet in the rain, Kayo hung it to dry in the room associated with the ghost rumor to hide it from her family. Eru feels sad that Rie is possessive of her belongings, but her mood lifts when she sees Rie carrying an injured Kayo on her back.
