As a bishoujo game, the selling points of this work are originally the proud and haughty young lady and the cute younger sister. Naturally, the voice acting of the protagonist Katagiri Yukiki cannot be without the participation of钉宫理恵(Rie Kugimiya). Moreover, with a lineup of top voice actors such as Aya Hirano, Marin Inoue, Rie Tanaka, and Ryo Hirohashi, the charm of this work has been elevated again and again! One of the basic conditions for a proud character to sell moe is being wealthy. The protagonist Katagiri Yukiki, as the fiancée of Junichi, in reality, their relationship is terrible. However, due to parental arrangements and matrimonial agreements, in order to maintain the relationship between the two families, the two have to continue pretending to get along. And they agree that if they still cannot fall in love this way, then the engagement can be canceled. Then a series of harmonious school life begins... Both the director and series composition/script will be handled by Keitaro Motomura and Makoto Uesugi, who have worked on "School Days". It seems that the "harmony" of this work is indeed a major highlight...
