"Ai no Sono (Touch My Heart!)" (愛の園 ～Touch My Heart!～, Ai no Sono ~Tatchi Mai Hāto~, Garden of Love: Touch My Heart!) is the first single of the J-pop idol group Morning Musume subgroup Morning Musume Otomegumi. In addition to the title song and its karaoke version, the single also contains a Morning Musume Otomegumi version of the earlier Morning Musume song "Dekkai Uchū ni Ai ga Aru", which was originally a b-side on the single "The Peace!". Morning Musume Sakuragumi also did a version of "Dekkai Uchū ni Ai ga Aru" at the same time as Morning Musume Otomegumi on the "Hare Ame Nochi Suki" single.
