About
Autumn of the second year at Shohoku High School. In a classroom where a chilly wind blows through, Guest keeps their distance from others as usual. Despite receiving passionate glances from some girls as a cool "bad-boy handsome" type, Guest spends their daily life in calm indifference. Appearing before Guest is Kaede Fujimoto, a popular girl in class. They were supposed to be carefree friends of the opposite sex... Ren Shinomiya, the most popular guy in the grade, and his obsession; Nao Ogata, a modest girl with hidden feelings; and the change in heart of the most popular girl, Kaede Fujimoto. Guest gets caught up in a storm of jealousy and love.
