Korea's number one Park Seo-jin and Japan's number one Takenaka Yudai met as same-age music kings with completely opposite personalities. In the second episode of MBN's "2025 Korea-Japan Music King Battle," which aired on the 9th, the show recorded a viewership rating of 5.6% with a peak rating of 6.2%, ranking first among all variety programs broadcast on Tuesday. The program continues to see rising ratings and ranked in the TOP 10 for non-drama TV-OTT buzz and search responses for the first week of September, as announced by Fundex and Good Data Corporation.

Park Seo-jin and Yudai surpassed 1 million views on their preliminary stage performances, achieving the highest views in both countries. They attracted viewers' attention with their similar height, years of experience, and hairstyles. After an awkward handshake, Yudai said, "I never had a friend the same age among singers, so I'm really happy to meet you." Park Seo-jin briefly replied, "Me neither," showing his shyness.

Yudai expressed curiosity about Park Seo-jin and continued the conversation, to which Park Seo-jin said, "I am very shy and have trouble making eye contact." Yudai laughed and said, "Sorry for talking so much. I've never experienced shyness. But let's get along well." Yudai shared, "I like martial arts, so I was happy to receive the reigning king belt of 'Active Music King Japan,'" but Park Seo-jin quietly replied, "I don't like fighting. Actually, I don't like sports," making Yudai laugh.

Yudai continued asking Park Seo-jin questions, and Park Seo-jin found their conversation between two very different personalities interesting. When Park Seo-jin mustered the courage to ask a question, Yudai responded with ten answers, surprising Park Seo-jin. Their extreme chemistry electrified the scene.

Park Seo-jin moved Yudai by secretly taking care of him. He personally visited the Japan TOP7 waiting room to deliver coffee for Yudai and the TOP7, and showed sweetness by bringing Yudai's favorite food and handing it to the tired Yudai.

The production team said, "This week's broadcast will proceed with the announcement of the results of the first round of the main competition, followed by the second round. More thrilling and polished stages will unfold." They added, "Amid the fiery music national competition of the Korea-Japan TOP7, friendships are growing stronger. Please share in the atmosphere of the scene."

MBN's "Korea-Japan Music King Battle" episode 3 will air on the 16th at 9:50 PM. This program promotes cultural exchange between Korea and Japan through musical battles between the two countries. The meeting between Park Seo-jin and Yudai is drawing attention as a process of building friendship beyond simple competition. Their chemistry is highly anticipated in future broadcasts.
