Chiharu, who hasn't been tickled in a while, quickly became hypersensitive and spent the entire time laughing uncontrollably. Years of tickling practice seem to have made her extremely reactive—she bursts into laughter even from the slightest touch. This time things escalated even further, and she even came out with the unforgettable line: "My insides are ticklish!!!" Her adorable, sensitive reactions are not only entertaining but deeply soothing to watch. Highly recommended—be sure to check it out!
