Love Between Twins is Indivisible

My family moved next door to the Jinguji family when I was six years old. From then until I was in the first grade of high school now, both parents were on good terms, and the twin sisters of the Jinguji family that I grew up with were my close friends as if they were like my own family. Ryumi, the sister who looks like a boy, and Naori, the otaku sister who is cute on the outside. And I'm Jun Shirasaki, who isn't afraid of being sandwiched between beautiful sisters with different personalities. Although I'm a novice in love, I don't have a special relationship and the changes continue. "Why don't you go out with me? How about we try dating?" These words from Ryumi eventually led us into a strange love triangle.
