Su Wan and Lin Zhi are classmates and roommates. Su Wan is cold and talks little. Others say she "can't get in". Lin Zhinuan is gentle to people. It was the first time that Su Wan was treated like this by a person. She thought she was special. Later she discovered that Lin Zhi was equally nice to everyone. So Su Wan started to retreat. But every time she takes a step back, Lin Zhi takes a step forward. In the winter of her senior year in high school, Lin Zhi did a small thing, and Su Wan thought it was the answer. But when Lin Zhi left, she only said two words: "Congratulations." "She told me not to think too much. But what I thought was true - but to her, these were just things in the past." Three years. A love that was misaligned from the beginning. When the snow falls, it never falls for one person. But the ones that fell on the windowsill, I remember every piece.
Purpose: I think every friendship is worth keeping
