Not far?

I feel that some apartments are very close and should be in the same city. Participants can often be seen in different places in a short period of time.

No way! Like what apartments?

Elliot and his gang for instance.

Ultimately, you can assume that someone started it, and then other couples or individuals were ‘recruited’ from the circle of acquaintances. this automatically results in the spatial proximity

just the realm numbers that i know right off the bat:

4+25+33, 62+45+18+48, 65+87

I took a look at the ‘travel times’: there are rarely more than 20 minutes between starting/driving at home and arriving

I assume this is very incomplete
