Looking at how FUWAMOCO act to their genmates now compared to when they first debuted feels a little... Jarring. I've noticed that they're acting a bit friendlier toward their genmates nowadays?

FWMC Around Debut:
>They had mandatory weekly Advent collabs where they strictly adhere to the 'Two Hour Time Limit'
>They would either talk over everyone else or be completely silent during these collabs
>They would rarely do two-on-one collabs outside of the first month collabs with Biboo, where they didn't meld terribly well with each other
>Prioritize JP members over anyone else
>Cancel out on some Advent collabs
>Actively avoid interacting with anyone else on Twitter if they don't have to

FWMC Around 1st Anniversary:
>The 'Two Hour Time Limit' is still there, but seems to be a bit more relaxed
>They tend to meld better in full Advent collabs, taking care to not be as obstinant as they used to
>Frequently do two-on-one off-collabs with their genmates, aside from Shiori, which they addressed as something that needs to be fixed
>Do more to participate with everyone in Advent
>Constantly shill their genmates' streams

What happened? Did their time together in Japan change them?
What felt like a corporate mandated pseudo friendship seemed to morph into a real, genuine camaraderie.
Or am I just too autistic to see that they were friendly with each other from the start?
