Xiaoyuan and I met in high school.After going to college, I went to another place, and it was difficult to meet once.Due to my major, I usually have a busier academic career, so she often comes to me.In the spring of 2011, she came to Beijing again. We kept having fun and having sex as usual, and soon half a month passed away like quicksand between our fingers.On the day I left, I sent Xiaoyuan away. When I came back, I felt a little sad.
