Group incest

when a friend has started dating his friend ex whilst staying in the friend group as everyone involved, this also includes people in the group that like other people in the same group but are friends with the other ex. Breaking the bro code simultaneously.

steve goes out for Lara for about a month but it didn't work out, after a few weeks Lara goes out with bob, committing group incest but not severely. However, as they were dating steve was simping for Lara clearly prioritising plans with her above everyone else clearly committing group incest. All in all this situation wouldn't happen if the group would not commit group incest.
