Shizuku is a grade 3 student and a real bookworm. Her greatest dream is to become a successful writer. When she meets her classmate Seiji, the girl is fascinated by his tireless pursuit of making his wishes come true. The two become friends and vow to each other to one day make their dreams come true. Ten years later, however, Shizuku has given up being an author and instead works as an editor at a children's book publishing house. Seiji, on the other hand, who now lives abroad, is still striving to fulfill his dreams - even though the distance between him and Shizuku is growing.
