Kim Hyung-jun's mini album includes a 47-second introduction song, showcasing the overall feel of the album."My Girl (Korea edition) product info" YesAsia. Retrieved 16 November 2012. Both E-Tribe and RaDo produced two tracks each, including the lead tracks "oH aH!" and "Girl". Particularly, the former song was said to have "lacked popular appeal" initially by Kim, himself, but he then realized its potential afterwards. The album comes with two instrumental songs for the two lead tracks mentioned, while the Japanese release also includes the Japanese versions of those. Both the fourth and fifth tracks entitled "No Other Woman But You" and "Heaven", respectively, were penned by Kim Hyung-jun himself, dedicating the latter to the late Park Yong-ha. Park and Kim became friends during their Japanese promotions as they were both managed by Avex Entertainment. As Kim remembered Park who committed suicide less than a year before his album release, he started to think of the people whom he loved but who nonetheless had left him, leading him to write "Heaven" to express his feelings.
