Himawari

When Momo was in elementary school, she had her first crush on Haruo, who had a smile as beautiful as a sunflower. However, in the spring of fifth grade, they were involved in a traffic accident and when she woke up, he had disappeared. Four years later, in high school, she meets a classmate who resembled Haruo so much that it made her heart skip a beat. But he dismissed her brusquely, telling her she has mistaken him for someone else. A pure love story about a girl who has been single-mindedly in love with a boy since she was a child.
