I had a dream last night. I dreamed that the boy was going to study abroad. His unruly and willful girlfriend rummaged through all the items in the boy's room and found a large old box with a thick layer of dust on it. The girl blew and choked, "Gu Nian, come out and explain to me what these are?". As she talked, she flipped through the pages until she reached a thick diary at the bottom. Her slender hand seemed to be a little unable to hold it up after tentatively weighing it, so she carefully held up the thick diary with both hands. She opened the title page curiously, "Yan Qingbei, who likes you, will always like you until we see Hokkaido, Japan, and then we get married."
