Not all of the girls like each other, they just hide it better. However, though obviously the jp culture encourages professionalism, that is not the only reason.
Remember that JP has 4 times the members of EN, meaning that there's more room for stable cliques to form. Those can intersect and intercollab, but they don't have to, and provide enough variety for viewers to be satisfied so the chuubas don't need to seek out other partners they don't get along with that well. Meanwhile in EN, with just 10 people, 2 cliques forming are an obvious sight, as proven by the numerous rrats plaguing this board the past year.
I'm only hoping for EN3 and 4 so that the girls will have more collab partners, which may incentivize them to stream more. I was initially hoping the Myth girls would stay true to their promises and learn nipgo, but I've given up on them.
