The record of my sad and happy mood at that time may be superficial and not worth mentioning, but every word is my true heart, about the boy I can't forget over the years, about the trivial and interesting things in my life, about what I saw and heard along the way. Maybe you have the same experience as me here. There has been a boy whom I have been in love with for many years and cannot forget, and what is the thing in my life?
