College girl Kaguya Hinaki has a secret that she cannot tell anyone. That is... She falls in "crazy love" with Subaru from a 3-member video distribution group "Cosmic". One day, Hinaki, who really wants to date Subaru, receives a direct message from an account that she doesn't know. The owner of that account is Subaru! This direct message totally changes Hinaki's life.

Hanaori Kotono, a clerk working in a concept café, is a super fan of Cosmo from "Cosmic". She despises Hinaki and other people with "crazy love" and vows to be a "genuine fan" who doesn't bother Cosmo. However, she can't control her desire to get close to him. One day, she sees a post on social media sent by a fan who always badgers Cosmo.

The pure "love" of the two who fall in love with their "idols" eventually goes out of control and turns into madness...
