The first time he and she got to know each other was through a composition, and her first impression of him was through the words of a friend. A misunderstanding caused the distance between them to be distant for a time. When they met again, the misunderstanding was resolved. They thought their relationship could get closer, but the reality separated them again. When they reunited two years later, they no longer had any feelings for each other. They didn't even know how to say hello. They became so-called familiar strangers... Growing up? Love? Destiny? You can't start all over again.
