A manga that centers on Sasara's route from the visual novel To Heart 2 by Aquaplus.
The story revolves around a high school student, Kono Takaaki. He spends high school days in spring with girls, such as the childhood friends, Yusuhara Konomi and Kosaka Tamaki, and he encounters various girls of unique personalities. The name implies it is a sequel to “To Heart”, but there is no relation between them except that the story of “To Heart 2” takes place two years later at the same school of "To Heart".
Akari is a cute but somewhat inhibited teenage girl who attends high school with her childhood chums, Hiroyuki and Masashi. Though she regards these two along the lines of siblings, Akari finds her world becoming troublesome as her adolescent affection for the generous and warm-hearted Hiroyuki begins to grow onto something more. The complications only thicken when a beautiful senior, Serika Kurusugawa, steps into the picture. Akari finds her solution in an unlikely place: An android named Multi, who happens to be training to become a full fledged maid robot, just might be able to use her machined mind to help Akari overcome her shyness and win Hiroyuki's love!
