Jung Hae-in Takes On a Wild Acting Challenge Against Kim Dong-hyun on 'Nollaun Saturday'

Jung Hae-in is back on Nollaun Saturday, and this time he comes armed with a new strategy and, apparently, a sensitivity to praise. The episode airing this Saturday features the actor alongside Ha Young and Heo Sung-tae, and early previews suggest it runs well past polite celebrity chat.

On his first visit to the show, Jung Hae-in won over the studio with a string of sweet, disarming one-liners, even securing a "one-shot" promise from co-star Jung So-min by pledging to help her eat the food. This time around, he admits upfront that he is leaning on his fellow guests. "Today I think I'll rely on Ha Young and Heo Sung-tae," he says, which is either humility or a tactical sidestep from a man who knows exactly what he is doing.

Ha Young, making her Nollaun Saturday debut, wastes no time finding her footing. The actress presents as a high-energy extrovert with zero warm-up period, and she mirrors Jung Hae-in's earlier promise almost word for word, declaring she will be the one to help him eat. The callback lands well, and her chemistry with the cast builds quickly through the episode.

Heo Sung-tae adds a different texture. He mentions taking on the best villain role of his career in an upcoming project, but spends most of the interview segment as a visibly shy, introverted presence, which plays against type in the best way. The gap between the intimidating roles he takes on screen and the bashful energy he brings to the studio is genuinely entertaining.

The episode's appetizer game is a new format called Tell Me One After Another: Film and Drama Edition, in which two teams race to chain answers in a category. Jung Hae-in captains the "This" team and Heo Sung-tae leads the "That" team. Jung Hae-in's choice of teammates reportedly catches everyone off guard and briefly unsettles the room, which is a small but reliable signal that the editing will pay it off.

The main game segment gives all three guests room to run. Heo Sung-tae chases an underdog arc, reversing expectations after a slow start, while Jung Hae-in and Ha Young stay vocal and build a visible rapport throughout. Then comes the moment the preview has been circling: Jung Hae-in, who claims to have an allergy to compliments and blushes visibly when the studio audience cheers for him, pivots almost immediately into a full acting challenge with Kim Dong-hyun, a variety fixture known for his aspirations as an acting student. The two trade characters back and forth, and the result, by all accounts, reduces the set to laughter.

The dessert game, Guess the Love Scene, is also new to the show's rotation. Contestants are shown stills from famous film and drama love scenes and must identify the title. The format invites creative wrong answers as much as correct ones, and the show promises elaborate performances and comedic ad-libs from everyone involved. Heo Sung-tae's past photos also surface during the segment and, according to preview materials, cause enough of a stir to stop the studio cold.

Ha Young ends the episode having mastered the show's signature dance, which is a small but telling marker of how thoroughly she adapted for a first-time guest. Jung Hae-in, for his part, delivers a surprise performance that the show describes as something viewers have not seen from him before. Given how carefully he tends to manage his public image, that claim is worth taking at face value. Nollaun Saturday airs Saturday on tvN.
