RIIZE 라이즈 '쇼선생의 일본어교실' @RIIZE 3RD ANNIVERSARY FANMEETING - Ch. RIIZE : ON AIR

What happened

RIIZE’s Shotaro plays a Japanese teacher in a segment from the group’s third-anniversary fan meeting, “Ch. RIIZE: ON AIR.”

In the Korean comments

The classroom premise continues in the comments as exaggerated student talk. One comment reads, in translation, “I listened to this and passed JLPT Level 1”; another says, “His face is so handsome that I couldn’t understand a word. Please give me a makeup lesson.”

What the words mean

사심 아니에요 (sasim anieyo, “I have no ulterior motive”) literally denies any personal agenda. After a commenter promises to study hard and asks “Taro-sensei” to teach forever, however, it is a casual, teasing denial that makes their obvious admiration part of the joke.
