So what exactly is going on?

The original plot for this game revolved around a particular Fixer, known on the streets only as "Omen", who has contacted you in the past to do a little job for them.

Then a second small job.

On a third job, you were paired with someone else to do a slightly bigger task. (One of the other PCs)

With the fourth job you were again in a pair, but with someone else. (A different one of the other PCs)

On the fifth you ended up in a team of three people. (One of the other PCs you have worked with previously and one you haven't)

Then a big job came up that needed a team of five people. You discovered you already knew three of the other four people, and the job went really well.

Omen, whoever they are, seemed really pleased with the way you all worked together, and promised more big paying missions in the future for the group. None of you have actually ever met with Omen in person, all contact has been via comms or the internet using virtual reality meeting spaces.
