The narrative centers on high school student Kono Takaaki. He spends his spring semester at school with girls, including childhood friends Yusuhara Konomi and Kosaka Tamaki, and meets various other girls with distinct personalities. Although the title suggests it is a sequel to “To Heart”, the two works are unrelated, except that the story of “To Heart 2” is set two years after “To Heart” at the same school.
