When we first met, Ren Xi was still a high school student, sitting boredly in the corner of the last row, playing with an eraser, half leaning against the dirty wall, lowering his eyes; when we first met, Wen You was still a teacher who had just graduated and entered the campus for the first time, and it was not very suitable for him. Walking into the classroom with high heels on their feet and a smile on their faces, a gentle voice filled the air: "I will be your new teacher from now on, and my name is Wen You." Their first meeting was ordinary, but it established a love that will eventually wither.
