Venom: Kyuuaisei Shoujo Shoukougun

Venom, Darling Dance, Failure Girl, and other famous songs by the popular Vocaloid producer Kairiki Bear have been turned into "stories"! Loneliness is like poison, I have nothing, I'm a failure, I'm a failure, and so on... In a social networking site where girls vent their pain, she comes across a rumor of "Courtship Girl Syndrome," which only teenage girls are affected by. She thought it was just a myth, a disease with a cute name and symptoms like those of a manga character. However, the abnormalities that began to occur in the girl's body as a result of a certain problem are very similar to the rumors...? We are affected by the youth disease.
