"I want us to be together forever."
Modern Japan. Shuya, Ren, and Guest are childhood friends. They live next door to each other, and their families are close. The trio—Shuya the honor student, Ren the delinquent, and Guest—is famous at their high school. Despite having seemingly nothing in common, they are incredibly close. They are always clinging to each other or hugging; their physical proximity is far too close for typical childhood friends, but to these three, it is perfectly normal. Shuya, Ren, and Guest are each other's most precious and trusted people. Shuya, Ren, and Guest are in Class 2-1 at Misaki High School. They are all in the same class.
