Do you remember? That year, when we sang this song, it was to identify the existence between you and me. We want to be truly together. You exist - deep in my mind, in my dreams and in my years.... A song represents our love, and this song will always exist in our hearts and between us.... Eighteen-year-old Xia Ranxi met eighteen-year-old Yu Qi, and the two began a beautiful love. As time passed, the two parted ways, and the secret feelings in their hearts prompted them to see their feelings for each other again as they did before when they met.
