The story takes place in a boarding school called Dalia Academy, which stands on an isolated island and is not easily accessible to outsiders. Dalia Academy is divided into two factions - the East and West factions. In fact, there is a war between the two countries, so the students of the two countries are studying in the same academy, and the atmosphere is very tense. The students of the East and West have their own apartments, and Inuzuka Rurenxiong (voiced by Ono Yuki) and Juliet (voiced by Chino Ai) are the two leaders of the students of the two countries. However, what no one knows is that these two people are hostile to each other on the surface, but they are actually underground lovers in secret love. Once this relationship is known to others, the whole school will fall into chaos.
