I think for all of us, we will never have another 2003; it is impossible to have another elementary school; it is impossible to have another first love; it is impossible to have the joy and happiness of the past. Yesterday, and the previous second, it is impossible to go back, let alone us 13 years ago. Sometimes we have to admit that life turns out to be a sitcom that cannot be played back. Meatball, White Shirt, Minjiji, Amen... Each of them is no stranger to each other. They all have the most fond memories, and they all have a memory about "sunshine". Their youth has their common face, common past, common them, and common most fond memories.
