The "Respond 1997" bus writing is grabbing attention.

Actor Lee Shiun uploaded a photo of a bus on his twitter on Wednesday saying "My hidden, shy side song by. Countryside Sungjae bus."

In the uploaded photo, the bust that Sungjae rode to change his grandmother's light was in place.

On the bus, there were writings of the station but the first letter of each station created the phrase "Big Epic Respond 1997."

Internet users have responded commenting, "They give small humor," and "They are really something."
