Aqua PLUS produced a game with the same title as this manga which is a classic dating game featuring Kono Takaaki, a high school student. Takaaki's time in high school is filled with spending time with girls including his childhood friends, Yusuhara Konomi and Kosaka Tamaki, as well as meeting other girls with distinctive personalities. Despite being called a sequel to "To Heart", the only similarity between the two is that "To Heart 2" takes place two years after "To Heart" at the same school.
