Actor Yoo Yeon Seock, attention on science and engineering family ”Father is an engineering professor, brother is a mathematics lecturer”... Guest is ”IVE” An Yu Jin = ”Whenever I have free time”

Actor Yoo Yeon-seok mentioned his family background in science and engineering.

On the third episode of SBS's "In Your Free Time," Yoo Yong-seok and 2MC Yoo Jae-seok shared their good fortune with their "free time friend" Ahn Yoo-jin of the group "IVE" at yoga, a boutique, and even a flower store.

When Yoo Yeon-seok mentioned that he was celebrating his 40th birthday, Ahn Yoo-jin, who was born in 2003, expressed his congratulations while looking perplexed.

Yoo Jae-suk, Yoo Yong-seok, and Ahn Yoo-jin met with their first "gap" masters, yoga teachers.

They then moved on to have lunch, where Yoo Jae-suk, who had udon noodles, showed a stormy mokbang (eating broadcast), saying, "Udon, I haven't eaten in a long time. Ahn Yoo Jin and Yoo Yeon Suk also began to eat, savoring the firm noodles. A bet on the cost of the meal ensued, and the person with the longest noodle grabbed with chopsticks decided to serve.

The noodle chosen by Yoo Jae-suk was incredibly long. Seeing this, Ahn Yoo-jin said, "Thanks for the food," which drew laughter. The next noodle chosen by Ahn Yoo-jin was about the middle length. Finally, Yoo Yong-seok chose the shortest noodle and Yoo Jae-seok paid for the meal.

When asked about the sibling relationship, Ahn Yoo-jin revealed that he has an older sister, adding that they became closer as adults.

Yoo Yeon-seok, who has an older brother, shared Ahn Yoo-jin's story and said, "I really fought a lot too. My brother is now a math instructor. My father is also an engineering professor, and (my brother) lectures in online classes," he explained. When asked if his brother is a star lecturer, Yoo Yeon-seok said, "Next to that," which made him laugh.
