Netflix is pressing ahead with its adaptation of the hugely popular web novel «Solo Leveling» (나 혼자만 레벨업). According to Korean media reports, Rain (Jung Ji Hoon) and Lee Sung Min may be joining the cast of the project.

However, details on Rain’s casting remain conflicting. As of 9 July 2026, several Korean outlets, including Xportsnews, reported that Rain had confirmed his involvement. Yet his agency, Rain Company, issued an official statement the same day, saying that «participation in the drama «Solo Leveling» is still under consideration, and no decision has been made so far».

The series is based on the web novel of the same name by Chu Gong, which has already been adapted into a webtoon and an anime. By July 2025, the global reach of the franchise had surpassed 14.3 billion cumulative views. The story unfolds in a world where mysterious gates have appeared, opening passages to parallel dimensions. Some people have awakened supernatural abilities and are known as hunters. The protagonist, Sung Jin Woo , is an E-rank hunter – the weakest among his kind. One day, he finds himself trapped in a dungeon but miraculously survives. After this incident, a mysterious program called «The System» selects him and grants him a unique ability to level up after each victory and turn defeated enemies into shadows. Sung Jin Woo sets out to uncover the secrets of the dungeons and the true origin of superhuman powers.

The lead role of Sung Jin Woo will be played by Byeon Woo Seok, known for his work in the dramas «Lovely Runner» and «Perfect Crown». Earlier reports indicated that Han So Hee and Kang Yoo Seok are in talks to join the project as Cha Hae In and Yoo Jin Ho, respectively. Kang Mi Na is also being considered for a supporting role.

Rain has been offered the part of Baek Yoon Ho – an S-rank hunter and the head of the White Tiger Guild, who monitors the protagonist’s growth and attempts to recruit him. 

Lee Sung Min, according to media reports, may take on the role of Go Gun Hee, chairman of the Hunters Association.

So far, however, no one except Byeon Woo Seok has officially confirmed their participation. This is somewhat unusual, given that filming for the drama began in May 2026 and is scheduled to last three to four months. 

The first season will consist of seven episodes. 

The drama’s premiere is planned for 2027.
