This is the debut game for FIANCEE. Yuusaku confessed to Miina and they became lovers. She was an ojousama who had lived a sheltered life, but now they will be living together. However, it doesn’t all go smoothly, with their neighbours being suspicious of them, their classmates learning about them living together and other love rivals appearing. It also doesn’t help that he doesn’t understand girls well nor does she understand boys. The only thing that works to their favour is their strong love for each other. Will that be enough to overcome all their obstacles and come to a happy end?
