Why are there so few scenes of Orfila in "Sister Who Rides the Wind and Waves"?

Orfila, the younger sister with the fewest shots in the program. In the second program, Orfila had only four chances. In fact, before the program started, no one expected that Orfila's sense of existence would be so low. Because Orfila is the host after all, she should be more active in mobilizing the atmosphere and communicating with each other. But I never expected that Orfila seldom spoke or even didn't speak in the program. Of course, if you think about it carefully, it is also in line with Orfila's character.
