Fans will be able to see ONE on his first ever variety show appearance this week! (Apart from 'Show Me The Money', of course.)

On this week's 'Salty Tour', the cast members will be joined by a special guest, ONE, for their Singapore vacation. Even though ONE is almost 20 years younger than the main MCs Park Myung Soo and Kim Saeng Min, as well as several years younger than Park Na Rae, he was still able to get along with the cast well, according to reports. 

In the preview for the upcoming episode, the members board a cool, refreshing river cruise, finding "healing" in the perfect, sunny weather and the river breeze. Park Na Rae also causes laughter by setting out to take a photo of the men with the river in the background, but cutting out Kim Saeng Min in the end to capture only the "handsome" men. 

You can catch the episode on March 3 at 10:30 PM KST on tvN.
