Maybe he too busy with his work assignments on top of running his business.. Also, often at times Jin would appear together with Natalie from UK. Perhaps their modelling agency are pushing for similar exposure.. even if not together in same episode, ‘neighbouring’ episodes would have either one or the other. Leading to speculation that the agency is ‘pushing’ for them to be present together on the same recording day and try to film at least 2 episodes. Estimated each recording day (typically weekend like Saturday) can film 6-8 episodes estimated (1.5-2 weeks of 1 hour airtime, commercials included)
