Similar to Hunter x Hunter, World Trigger, Tower of God, The God of High School and Berserk, Solo Leveling manwha’s serialization was plagued with hiatuses due to Sung-rak’s health issues.

His chronic illness first manifested back in August 2019, at which time he was forced to take his first sudden hiatus – this one lasting a total of four weeks – between the release of Solo Leveling’s 85th and 86th chapters.

He would take his next hiatus in March 2020, around the release of chapter 110, though at the time provided no further details regarding the reasons for the break.

In November 2020, Sung-rak’s chronic illness would arise once again, forcing the D&C Webtoon Editorial Department to announce yet another break for the popular manhwa. that chapter 128 of the Solo Leveling manhwa would go on another sudden hiatus.

This time, D&C explicitly noted that one of the reasons for the series’ delay was to allow for “recovery of the artist’s health“.

In 2021, as the end of the series was fast approaching, Solo Leveling’s ever-increasing number of hiatuses began to make fans feel as if something particularly serious was amiss – in hindsight, it is now obvious that it was Sung-rak’s chronic illness starting to catch up with him.

The first hiatus of the year was announced in June, with D&C informing fans that the upcoming 156th chapter of Solo Leveling would be delayed because “Jang Sung-rak will be absent due to his health reasons”.

Unfortunately, the artist’s chronic illness was only continuing to take its toll, and just a few days later D&C announced that his hiatus had been extended by a week “to restore Jang Sung Rak’s health“.

Though he eventually found the strength to continuing working, his return was short-lived, and in September 2021, he was forced to take yet another two-week break – which sadly would eventually come to be known as his final one before his death.
