It turns out that there is such a person in this world. When you think of him, tenderness like floating clouds, a touch of joy, and a faint pain will pass through your heart; there will be a person hidden in your heart, a pain that you can never blurt out, silently caring about, and deeply blessing; there will always be a deep feeling integrated into life, like sugared coffee, sweet and bitter, you can't leave, and you can't forget.
