Hawthorn Doctor

I thought being rejected would be a shock enough, but my fiancée's ex-boyfriend came to visit me again. What's even worse is that this guy is still my good brother. Well, because he was married and had been begging for treatment for his child, Mo Xi, a doctor, had to put aside the holiday temporarily, and the three of them got together again. However, is this really okay? Why do they feel like the two of them are getting closer and closer.
