'My Little Old Boy' has drawn attention by releasing four character teasers full of personality featuring Lee Sung-min, Bae Jung-nam, Kim Jong-soo and Kim Sung-kyun, who traveled to Kazakhstan.

The SBS variety show 'My Little Old Boy,' which airs on Feb. 1, will reveal the Kazakhstan trip of actors Lee Sung-min, Bae Jung-nam, Kim Jong-soo and Kim Sung-kyun. The four have maintained a long friendship since working together in the 2017 film "The Sheriff," drawing interest in the "real brothers" chemistry they will show in the unfamiliar setting of Kazakhstan.

Meanwhile, the teaser video released ahead of the broadcast raises expectations by capturing the four's warm "real selves" charms, which contrast with the images they showed in their works.

Lee Sung-min took charge of the trip's accounting. In the released video, Lee Sung-min grumbled, "Why are you telling me to do (the accounting)?" yet showed a tsundere charm by meticulously keeping track of even minor expenditures. His strict money management, saying "Do you even charge money to use the bathroom?" eventually prompted Bae Jung-nam to give up, saying "I just won't go," which provoked laughter.

Bae Jung-nam, the youngest who served as the guide, showed a clumsy side that contrasted with his overflowing enthusiasm. Bae Jung-nam led the elders and ambitiously took on the guide role, but he repeatedly exposed gaps, such as forgetting to pack his bag and mistaking discounts for freebies, causing anxiety among the elders. Bae Jung-nam is expected to create unpredictable situations that will bring both tension and laughter to the Kazakhstan journey.

The eldest, Kim Jong-soo, displayed a "fearless straight-ahead man" charm that overwhelmed his younger companions. Unlike his frightened brothers faced with thrilling activities like the high-altitude swing, Kim Jong-soo enjoyed the trip, repeatedly shouting "I love it" as he cut through the air, giving viewers a refreshing sight. Reports say he also mediated between bickering younger members and took care of them frugally and warmly, showing the dependable side of an eldest brother.

Kim Sung-kyun showed the care of someone who packed homemade side dishes such as stir-fried anchovies, scorched rice, and pickled chili paste for this trip, volunteering for the role of "pro homemaker." At the local market, he even managed to get free items after fierce haggling with merchants, showing maximum survival skills and offering a surprising charm different from the intense image he has shown in his works.

The bumbling travel story of four people with different personalities in the unfamiliar land of Kazakhstan will be revealed on My Little Old Boy, which airs at 9 p.m. on Feb. 1.
