while the talent management division became iHQ (also known as SidusHQ). In 2004, SKT Corporation and Sidus HQ have collaborated to create a mobile drama called 'Five Stars'. On the 25th, the protagonists of the mobile drama 'Five Stars' were revealed through SK Telecom's June. The five male protagonists of 'Five Stars' consist of four newcomers discovered by Sidus HQ and one individual selected by netizens who visited a specific website between July 10 and 25. Set at a rural school, The drama, set to release in early October, features Gong Hyo-jin as the female lead. The characters included the rebellious Si-wool (Yoo Ha-jun), the cheerful playboy Jae-gwang (Jung Kyung-ho), the tough guy Jin-woo (Kim Hyung-min), the romantic Da-hyun (Jung Gyu-woon), and the adorable Ha-ru (Park Ki-young). The ending was decided by fan votes, in line with the nature of a mobile drama. 'Five Stars' was pioneer of an actor group, aiming to act together while pursuing individual activities. Except for Jung Kyung-ho, recruited from KBS talent, the others, mostly models, had limited acting experience. Despite being like unpolished diamonds, their tall and slim figures showcased promising potential. The drama consisted of seven episodes but received significant effort, comparable to a movie. They underwent three months of intense training at the Seoul Action School for action scenes. Appearances were made by several senior stars from Sidus HQ, such as Bin, Jang Hyuk, Ji Jin-hee, and Kim Sun-a, as well as cameo appearances, including Kim Soo-ro, Yeom Jeong-ah, Kim Sung-soo, and Gong Yoo. The OST, composed by Danny Ahn from god, premiered on a music cable channel in mid-September. In 2005, iHQ acquired

in partnership with SK Telecom China in 2007. The branch serves to promote the activities of Korean stars in the Chinese market. In 2010, Sidus regained ownership of the company that had previously been acquired by SK Telecom in 2005 by repaying the money. This decision was influenced by the contrasting perspectives and emotions about their respective businesses held by the two companies. Concurrently, the Sidus family embarked on a path of self-sufficiency. As the market environment demanded changes, smaller, family-oriented management businesses started to emerge. Former managers took the initiative to establish their own independent management companies, namely King Kong Entertainment, Fantagio, Management Soop, and Blossom Entertainment. The Sidus family's spin-off not only created an additional growth engine but also established a collaborative system. In 2011, SidusHQ stars are attracting attention by producing a 'Love Sharing Hanbok Calendar' to practice warm love for neighbors. In 2013, iHQ acquired 60% of shares in Wisepeer Inc., owner of the music site monkey3. It also became the biggest share holder (50.01%) in
