The whole "advent hung together in japan, this is why they have chemistry" is pure cope. Like, how much time could they have spent together realistically? a couple of months at best considered the graduations. And even if they spent 9 months, you can't force people to be friends.

Advent is still together because, as simple as it is, they keep together, and they keep together because they all know this is the best it will ever be for them.
FWMC have been grinding as idols for what now, a decade? this is their idol gen and they are not letting it go. Same for Nerissa with her singing, this is HER story after being second and third fiddle to her sisters for her whole life.
Shiori is getting her pension, and losing this means losing everything. No funds to do her video projects, no money to buy clothes and cosplay.
4 fifths of advent has no prospect outside of advent. The only one that could make a living outside of the box is biboo, but she's committed enough that she moved to Japan.

Compare that to myth, where they all have personal success be it PL or solo stuff. Promise, who all could go indie tomorrow and be successful.
Or even justice, with Raora and ERB would could make a living and a killing out of PL stuff, and this is how you get CCGG.
