The core of this broadcast is a gathering with a unique concept called ‘6th Grade Club’ led by comedian Yang Sang-guk. This was planned with the intention of bringing together men who had been given a somewhat low rating by a marriage information company and consummating marriages based on sincerity rather than conditions. As the head of this group, Yang Sang-guk scrutinized the applicants' faces and introduced a strict verification process in the form of an audition to achieve the result of an actual marriage. Rather than simply considering external conditions, he focused on strengthening the club's internal stability by closely observing applicants' attitudes and values ​​toward marriage. This setting served as an opportunity for viewers to think again about the way our society views marriage and the cruel grading system hidden within it.

While the audition was in progress, the person who immediately changed the atmosphere of the scene was actress Shim Hye-jin's nephew, Shim Jae-won. As he appeared, with his tall height and exotic mask, a strange tension began to fill the audition room. As soon as Yang Sang-guk saw his visuals, he expressed an honest sense of crisis, saying, “I’m already uncomfortable,” and then made an unconventional assessment, saying, “This person could get married right away, even tomorrow.” This was an element that maximized the entertainment tension caused by the introduction of a person who could be called ‘grade 1 in appearance’ into a group with a somewhat intimidating image of ‘grade 6’. Everyone at the scene responded that they were overwhelmed by his mere appearance, increasing expectations and curiosity as to whether he would fit in with the personality of this club.

Yang Sang-guk was embarrassed by Shim Jae-won's appearance, but he dominated the conversation by pushing him with his unique mischievous interview style. He tested the applicant's composure by repeatedly asking difficult questions such as, "Don't you think you're handsome?" or "Would you rather live with my face or with your own face?" In response to this, Shim Jae-won did not look embarrassed or offended, but responded humbly by saying, "It's not that bad," or showed flexibility in tactfully handling the situation by saying, "It's not something I can change at will." Shim Jae-won's coping style gave us a glimpse into his calm and mature inner self hidden behind his external splendor, and became a crucial scene that impressed viewers with his human charm that went beyond his simple handsome appearance.

As it was revealed that Shim Jae-won is the nephew of actress Shim Hye-jin, his appearance became the center of attention beyond a simple entertainment appearance. Shim Hye-jin had previously played a central role in the program by serving as the first sponsor of Shim Hyeon-seop's ‘Marriage Promotion Committee’, so the appearance of her nephew, who inherited her genes, created greater familiarity and interest among viewers. He showed an attitude of trying to prove his sincerity rather than relying on his aunt's halo, and showed concern about how to define and adapt to the unique environment of the ‘6th grade club’. This has become an important narrative that not only informs the public of the name and face, but also reminds us once again of the theme of ‘sincerity toward marriage’ that the program ‘Joseon’s Lover’ aims for.
