Group Boynextdoor (BOYNEXTDOOR) members Seongho and Myeong Jaehyun appeared as guests on "EXchange 4" and made an impact.

Seongho and Myeong Jaehyun appeared as guests in episodes 3 and 4 of the TVING original "EXchange 4," which were released at 8 p.m. on the 8th. The two introduced themselves as the T (thinking) and F (feeling) types among MBTI types and immersed themselves in the cast's narratives in their own ways. They continued vivid reactions, feeling sorry when a cast member's heart was divided and empathizing with the situations they faced. When deducing X, they responded candidly with comments such as "my head feels like it's going to explode" and "my dopamine is rising," adding to the fun.

Especially as a team beloved for vivid lyrics they write themselves, they sharply expressed the psychology that lovers feel, drawing attention. When a cast member made subtle moves, they received praise from the panel with lines such as "it's not jealousy; it seems they're fighting the feeling of 'I'm not jealous' because their pride was hurt." The panel did not spare their admiration for the two members' performances, saying, "It's at 'EXchange GPT' level. Their analysis is so good and they view things so coldly that I want to steal their lines."

They also shared their impressions of participating in the "EXchange 4" OST. Seongho and Myeong Jaehyun said proudly, "Lyricist Kim Ina wrote lyrics that suit the 'EXchange' series well. It feels good to hear our song play in the situations we imagined." "Ruin My Life," sung by Boynextdoor (Seongho, Liu, Myeong Jaehyun, Taesan, Ihan, Unhak), has been greatly loved, appearing on YouTube's rising music video chart from its release on the 1st through the 8th. The song is inserted into key scenes where the cast's emotions entangle, enhancing immersion.

Boynextdoor will release their mini fifth album "The Action" at 6 p.m. on the 20th. The record reflects their aspirations for growth and contains a bold mindset to move toward "a better me." The title track "Hollywood Action" is a song that shows a confident, assertive attitude like a Hollywood star. Expectations are focused on their comeback as they continue their successful run.
