Hinano Segawa Appeared in the Busan, Hua Hin, Graduation 2025 in Seoul, Summer Vacation 2025, and Graduation 2026 seasons of "Kyou Suki." Since she has graduated high school, she can no longer appear on the show. Currently a 1st-year university student (19 years old). Height: 163cm. From: Nagasaki Prefecture. In the Graduation 2026 season, which was her final journey, she was almost entirely devoted to Keisuke. She confessed her feelings at the end but was rejected. She concluded by saying, "Kyou Suki was the best part of my high school life." Initially, she was interested in Ryosuke, but ultimately chose Keisuke. She used to call him Keisuke-kun but now calls him Kei-kun. She started with a bob cut but grew it long starting from the Summer Vacation 2025 season. She has a bright, incredibly kind, big-sister personality and prefers younger guys. She is also known as a big eater and consumes a lot of food. Fans call her by the nickname "Hinapon."

Name: Keisuke Nakamura Appeared once in the Graduation 2026 season of "Kyou Suki." Currently a 3rd-year high school student (17 years old). Height: 173cm. From: Nagano Prefecture. There were rumors he would return as a returning member for Summer Vacation 2026, but he consulted with the staff, saying, "Even if I continue on a new journey, I don't think I could fall for another girl. Is it possible for me to meet Hinano-chan in Paris one more time?" Keisuke only appeared in the Graduation 2026 season. When he debuted as a new member, Hinano, a returning member, told him her first impression was, "The other one is Keisuke-kun!" On the final day, a girl named Sawa also confessed to him. Unable to decide between the two, he ended up rejecting both, though his feelings for Hinano-chan were actually stronger. After Graduation 2026 ended, he couldn't forget Hinano.
