Lee Kwang Soo found himself in an unexpected situation after an ordinary message to a fan accidentally triggered a blocked term associated with controversial online slang.

On October 10, screenshots from the fan communication platform Bubble showed Lee Kwang Soo responding to a fan who said they had argued with a younger sibling and wanted some comfort.

He replied in a warm and casual tone, essentially telling the fan how cute they were and joking that, with time, someone might want to pinch their cheeks.

However, part of the Korean phrase he was typing was automatically blocked by the platform. Confused, Lee Kwang Soo separated the syllables and asked, *“Why is this a banned word?”*

He then reportedly searched for the term and shared results showing ordinary dictionary meanings, which appeared to leave him even more puzzled.

Lee Kwang Soo reacted, *“Why is this?”*

A few minutes later, his tone changed after apparently realizing why the expression could be sensitive.

He wrote, *“I took it back,”* before adding, *“Now I’m completely awake.”*

The blocked term has regular dictionary meanings, but it has also been used by some controversial online communities in South Korea as derogatory slang connected to the late former President Roh Moo Hyun.

Based on the conversation shown in the screenshots, Lee Kwang Soo appears to have encountered the term unintentionally while writing a common Korean phrase rather than deliberately using the controversial meaning.

The available screenshots also do not show exactly what explanation he later received. However, his quick follow-up messages suggested that he recognized the issue and immediately tried to correct the situation.

What began as a lighthearted attempt to comfort a fan ultimately turned into an unexpected lesson about a word filter and the controversial meaning attached to an otherwise accidental combination of Korean syllables.
