I just don't know anymore if I want Yuetao to cuck her scumbag husband with Ruby, with Mrs. Yan or with Butterfly Dream. Maybe with all of them, one at a time? (Or together, I'm not picky...)
What about the little girl selling needles and thread? Too young for you?
Lol, kidding. :P
Seriously now, be it Ruby, Mrs. Yan or Butterfly Dream, all seem to have realized something BD states explicitly in the 2nd or 3rd chapter — that is, men can not be relied upon. Yuetao is making quick steps towards the same conclusion — if she isn't already there! Thus it's possible for her to romance some or all of these disillusioned women in the future...
(I say "in the future" because for now BD is the only one she seems to be developing feelings for!)
