The summer when Xu Yi met Ning Suchuan was the most unpleasant vacation. The sun is pulsing like a drink, surging with excitement, hanging high in the sky, tireless. On the road, you can really fry eggs. As Xu Yi often said, if you suddenly hear a bang on the road, please don't be afraid, it must be that she has been exposed to the sun and exploded. And Ning Suchuan is the dry ice that makes Xu Yi feel cool in this kind of weather. He was like the sunshine in spring and the rain in summer. Later, after they became the most important people to each other, Xu Yicai felt that he was also like frost in autumn and wind in winter, biting and cold, piercing every bone simply and directly.
