[... In projective geometry, two parallel straight lines will intersect at infinity, and the intersection point is called an infinity point...]
Li Yiran once asked Wang Minggang if they would have an infinity point. Wang Minggang smiled and answered her that he was always by her side.
Wang Minglang seems to have always been by Li Yiran's side. They have witnessed each other's youth, growth and transformation, and were each other's light and warmth in each other's darkest moments. He led her to see a wider world, and she also made him believe that unreserved love in this world may have nothing to do with blood ties.
I love you, it can be a word of love when we are in love, or it can be a shackles when we are not in love. If there is a possibility of forging a hard edge in this sweetness, then shouldn't this sweetness exist in the first place?
