In the episode, Song Il Gook feels total shock after getting on the scale. It turns out he put on a lot of weight this winter. Unaware of his dad’s feelings, Min Gook asks, “Dad, you got bigger?” and makes Song Il Gook despair a second time. Therefore, Song Il Gook and the triplets head to a nearby park and take their first step into dieting.
In the preview stills, the triplets come out marching with their matching exercise outfits and sun visors. They show off their cute martial arts skills as they wave their adorable arms and legs around and follow Song Il Gook’s exercises to motivate their dad even more.
You can see more of the triplets when the episode broadcasts on April 19.
