While playing a shuriken-throwing game, Ryouya turns down a bet that could've made him have to follow the twins' orders. Riona manages to hit the target with every throw. Reona also succeeds after being told to picture Ryouya as the prize, then both of them try using that excuse to claim him for themselves.
After playing, Ryouya thanks them since the day's been genuinely fun. For the first time, free time during a study tour doesn't feel like a punishment.
That night, Reona and Riona come to Ryouya's room even though visits to the opposite gender's room are banned. When his roommate comes back, they pull Ryouya into the closet with them. The cramped space forces them all close together, leading to a bunch of accidental
touches that get turned into more teasing material.
Reona eventually calls her friends to get everyone in the room to step out. Once the room's empty, the three of them manage to sneak out of the closet without getting caught.
On the last day, they visit Sanjusangendo and Fushimi Inari. On the bus, they try out a compatibility app. Ryouya gets a 95 percent match with each sister. He says the app shouldn't be taken too seriously, but secretly feels pleased about it.
While climbing up Fushimi Inari, Ryouya buys drinks since Riona's already exhausted. On the way back down, he sees a female tourist's phone fall and returns it to her. She hugs him as a thank-you.
The twins immediately cut in and start questioning him. They don't like that Ryouya looked happy being hugged by another girl. As punishment, the two of them hug him from the front and back until they're satisfied, even with a lot of visitors watching.
The three of them continue the climb and draw fortunes. Ryouya's result means bad luck will be followed by good luck, while the twins both get extremely good fortune. Before heading home, they buy matchmaking charms and write down the name of the person they want as a partner. Ryouya doesn't see the names and still assumes their choice would obviously be some popular guy.
After buying souvenirs and taking photos at Kyoto Station's sky corridor, they head back to Tokyo. Ryouya feels a bit sad the study tour's over, even though he'd wanted the whole thing cancelled before it started. On the train, Reona and Riona fall asleep while holding onto both his arms.
Back at their house, the twins talk about their real goal again. By staying close to Ryouya throughout the whole study tour, they want everyone to see their relationship as something normal. They believe a confession alone won't be enough since Ryouya's way too insecure. That's why they're working to make sure he has no reason or opportunity to pull away. The school festival will be their next move.
Ryouya himself gets greeted by Mio once he gets home. His sister can immediately tell from his face that this study tour was actually fun. But when asked about his relationship with the twins, Ryouya still thinks they don't see him as real boyfriend material. Mio just reminds him that the two rings they made him wear already say otherwise.
Back in his room, Ryouya still doesn't feel like thinking about the school festival. Even so, he's starting to hope it'll be just as fun as this study tour. He knows Reona and Riona will definitely end up overwhelming him again, but deep down, he actually wants to keep spending time with them.
