Have you ever imagined that you should both have your first love? Anyway, eighteen-year-old Chu Yexuan and eighteen-year-old Yuan Hang thought about it. Love at first sight appears in novels and movies, but love over time becomes more realistic, popular and everyday. I have thought about the time and place of countless encounters, and the reasons and backgrounds of falling in love countless times. That day, you came and broke into my world. Those fantasies took on color and became like idol dramas. I don't want to miss it, I believe this is fate. As long as you lead me along, I won't get lost or tired. This is the agreement, in this life and the next.
