>>97715848A rough armchair psychologist breakdown would probably go like this:
Three different sisters with three different dads who seem to just kind of drift in and out of the picture, and they have nothing else going for them. Nobody likes them, they live in a shitty trailer park walking distance from the nicer suburbs. The ONLY other girl in their age range is the one girl who gets any attention. They're three people with no structure, nothing to fall back on, and very little of their own.
The Eds don't get attention because of their personality or accomplishments, they get the attention because they're three guys who are weird enough that the girls think they have a shot, and the sisters have no real ideas on boundaries because the only relationships they have as a template are three dudes who are at best infrequently around and at worst just outright absent. They're going to FORCE a relationship that doesn't exist to be more than that but have no idea what it is they actually want or how to accomplish it.
