My girlfriend who I have been with for many years passed the intermediate accounting professional title exam. In order to prepare for the surprise marriage proposal at the celebration banquet, several brothers and I waited until late at night, but we saw her and her senior brother's official circle of friends. After being frustrated, I still wanted an explanation, but what I waited for was my girlfriend's accusation. Later, she would always leave me in front of that man. After my expectations were frustrated again and again, I decided to make this couple happy. If it doesn't belong to me, let it go.
