My girlfriend has a boyfriend who is her childhood sweetheart.
I asked them to keep their distance, after all we were engaged.
"Xia Fan, why are you so lenient? We have been like this since we were young."
Her "best friend" even directly sent me photos of them having sex.
But she didn't care.
"My best friend doesn't have a girlfriend, and we're not married. This is called mutual help."
Then I broke off the engagement and had a girl brother.
But she became anxious: "Do you not want me anymore?"
