You and I met each other in the most beautiful time, but after the passage of time, we became hopelessly desolate. That year, 16-year-old Han Yasi met 17-year-old Xu Yang. She always missed her past childhood and the family that failed to fulfill her wishes. When that boy entered her world carrying the sunshine, she could not feel the warmth.

When the truth is revealed, how can the ugliest reality be buried? In the sea of people, there will always be someone who leaves first. So, what virtues and abilities do I have? I ask you to understand. There are always some people who have never started but have already ended.
