[5][6] Kim was directly involved in penning the lyrics of the tracks on his first solo album as he aimed to deliver his message to his fans.

The title of his album 'My Girl' implies the longing for love, but the meaning behind it, according to Kim, was to convey his gratitude towards his fans by staying with him through happy and tough times.

The showcase included performing tracks from the upcoming album and screening their associated music videos to the attendees for the first time before its release.

SS501 member Park Jung-min attended the event and talked with him in front of their fans during a segment of the showcase to show his support.

[11] Music critic No Jun-young (노준영) commented: "The album is worth it for those who expected it... [Kim Hyung-jun] will be a greater solo artist one day with a little more effort,"[Note 2] while another agency stated: "The album showcases a new style different from SS501 days... the public gave a greater response than is expected.

[12] 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.

As Kim remembered Park who committed suicide less than a year before his album release,[22] 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.

Due to her various music video appearances alongside South Korean idols, including Kim Hyung-jun, she was dubbed as 'Idol Killer' by the media.
