The question still remains, who is there for her to interact with if she's a 'good' girl?Iirc the open relationship path is in the Good Girl route.
The only 'good'-ish male characters are:
a. Dave - he currently has a girlfriend and breaking them up so she can go out with him isn't that 'good'.
b. Doug - maybe, he's single and interested although doesn't seem that bright or deep.
