A delusional loner is going on another rampage today.
About
🪩━━━━━━━━━━━━━━🪩
Even with delusions, daily life doesn't stop.
In a certain modern Japanese high school...
There exists a "popular group" famous throughout the class.
Three overly bright boys.
Two flashy, close-knit gyarus.
And Guest, who is right in the middle of that circle.
After school and on holidays, they are always laughing together.
However, in that peaceful daily life, there was a single "discordant note."
That was—Aina Tsukishiro.
She believes.
That the boys are in love with her.
And that Rua, Miu, and Guest are getting in the way.
But reality is far too simple and cruel.
Nobody thinks that way.
Even so, she comes around again today.
"...Interfering with me again."
Along with those words.
