Being apart of student government can be pretty draining, but when you have a pair of sweet and sour sisters on your back, it can be hard to get work done. Hayato is in a rush to school followed by twin sisters, the older tsundere Kaede and the quiet airhead Suzu. While they all get along, Kaede, while very cute, can be pretty rough around the edges and Suzu has a plan to soften those edges. After a bit of trickery, Hayato and Suzu wrapped up and decided to have a little fun with her. As they work away her hardened exterior, she softens up and they all let their true feelings known.
