God Son Ho-young and Kim Tae-woo present a special summer.

A teaser video for the "2019 Son Ho-young & Kim Tae-woo Ho-bo" was released on the official SNS channel of S.J.Enter on Wednesday afternoon.

The teaser video released shows Son Ho-young and Kim Tae-woo, who met for a tour of the concert hall. Then Kim Tae-woo said, "Here?" in a cute way, while Son Ho-young is making those who see him as determined.

In particular, Kim Tae-woo looks at the waterfront of Lake 88 where the "Hoohaengbo" will unfold, drawing attention with embarrassment, saying, "What do you do with the water?" or showing Son Ho-young and Kim Tae-woo sitting on the waterfront with subtitles, "Are we going to fill this place?" highlighting the pre-announcement of the all-time Gukho River concert. 

Adding significance to the new year with different stage manners and audiences, "The Rainbow" opened its ticket through Interpark at 7 p.m. on Wednesday. 

The all-new "Hoohoo Alert" will be held at 8 p.m. on Aug. 23, 7 p.m. on Aug. 24 and 25 at the waterfront of Olympic Park's 88 Lake. For more information, you can check with S.J.Enter.
