Many times, I will recall the person I have experienced because of certain things, and he is the person who reminds me of many, many things. In today's life, there are many familiar scenes that remind me of that person and the days when he was by my side. Not just him, but also the countless little things, each of which appeared in my life, made me live step by step where I am now. Those things and those people are my most precious memories. The story is told in the first person, with primary school life as the main line, and the school year as the timeline, including winter and summer vacations, recording real events, and the names are all real. It tells the story of "I" meeting his first love in the fifth grade of elementary school. The two were in love but were embarrassed to confess. The people around "I" also quietly changed, and many things happened with my friends, which made "I" grow. In the end, first love became the best memory in "my" heart, and friends made "my" life more colorful.
