SM Entertainment Male Idol Swears During Live Stream

Yushi from NCT WISH caught fans off guard after accidentally slipping a mild curse during a recent live stream.

The controversy began when Yushi was streaming with fellow member Riku. While playfully reacting, Yushi said the Japanese word “kuso,” which is a casual curse like “damn” or “sh*t.” Idols usually avoid this kind of language on broadcasts.

Riku was instantly shocked and jokingly scolded him, telling Yushi not to use such words.

Riku: “What?”
Yushi: “Kuso.”
Riku: “What? Don’t use such words.”
Yushi: “Hurry up.”
Riku: “What?”
Riku: “Hang out with me.”
