Singer Crush gave fans a refreshing night to visit the Han River on a surprise busking.

Crush unveiled the "NAPPA" No. 1 pledge busking on Sept. 17 at Han River Park in Banpo, Seoul, for about 70 minutes through the official V LIVE channel of the finale.

Crush earlier made a pledge to busking guerrillas on the Han River as one of the top pledges to release his new song "NAPPA" during his first V app live. Since then, "NAPPA" has swept the top music charts, and Crush has made a surprise announcement of busking on the day and has gone to the Han River.

On the same day, Crush gave a gift-like time by playing a variety of popular hits from his new song "NAPPA," songs from his album and pop songs.

Crush sometimes mingled with fans even without accompaniment and captivated those who saw his fantastic stage manners. He also sang "How Deep Is Your Love," (a song he listened to a lot during hard times) to complete the event.

In particular, Crush said at the end, "Maybe we can have a concert this year. I will release a new album before that. I think my next album will have a song that goes well with autumn," raising expectations.

Crush's surprise busking turned the Han River into a concert stage on the day. Fans responded with enthusiastic cheers, gathering 2,500 people in just three hours after the announcement.
